  • Cayman’s Multidrug Resistance Assay Kit provides a convenient tool for studying the modulation of cellular multidrug resistance (MDR) machinery. The kit employs calcein AM, a cell-permeable nonfluorescent dye, which is cleaved intracellularly to yield the impermeant fluorescent molecule, calcein. This calcein is rapidly excluded from cells expressing the MDR proteins P-gp or MRP, and so functions as a probe for the detection of chemical compounds inhibiting MDR proteins. Propidium iodide is provided as a stain for marking dead or damaged cells. Cyclosporin A, a competitive inhibitor of MDR proteins, and verapamil, a noncompetitive inhibitor, are included as controls.

  • Myeloperoxidase (MPO) is a heme-containing enzyme and the most abundant protein in polymorphonuclear leukocytes (PMNs).{57128} It is comprised of two subunits linked by a disulfide bridge with each subunit containing a light and a heavy polypeptide chain. It can oxidize a variety of substrates and catalyzes the formation of highly reactive (pseudo)hypohalous acids and radicals including hypochlorous acid. MPO is stored in azurophilic granules of PMNs and is released from activated or necrotic PMNs, after which it can bind to and modify acidic serum proteins, as well as recruit additional PMNs. MPO also has roles in PMN apoptosis and antimicrobial defense systems, including neutrophil extracellular traps (NETs).{57128,23608,24590} MPO-deficient mice exhibit reduced survival in a polymicrobial sepsis model, increased susceptibility to experimental autoimmune encephalomyelitis (EAE), and increased atherosclerosis in mice also deficient in the LDL receptor and fed an atherogenic diet.{57128,57129,57127} Cayman’s Myeloperoxidase (mouse) Polyclonal Antibody can be used for ELISA, immunohistochemistry (IHC), and Western blot (WB) applications. The antibody recognizes MPO at approximately 80 kDa from mouse samples.

  • Cayman’s Myeloperoxidase Chlorination Fluorometric Assay provides a convenient fluorescence-based method for detecting the MPO chlorination activity in both crude cell lysates and purified enzyme preparations. The assay utilizes the non-fluorescent 2-[6-(4-aminophenoxy)-3-oxo-3H-xanthen-9-yl]-benzoic acid (APF), which is selectively cleaved by hypochlorite (-OCl) to yield the highly fluorescent compound fluorescein.{11242} Fluorescein fluorescence is analyzed with an excitation wavelength of 480-495 nm and an emission wavelength of 515-525 nm. The kit includes a MPO-specific inhibitor for distinguishing MPO activity from MPO-independent fluorescence.

  • Myeloperoxidase (MPO) is a member of the heme peroxidase superfamily and is stored within the azurophilic granules of leukocytes.{16902} MPO is found within circulating neutrophils, monocytes, and some tissue macrophages.{16923} A unique activity of MPO is its ability to use chloride as a cosubstrate with hydrogen peroxide to generate chlorinating oxidants such as hypochlorous acid, a potent antimicrobial agent.{16904} Recently, evidence has emerged that MPO-derived oxidants contribute to tissue damage and the initiation and propagation of acute and chronic vascular inflammatory diseases.{9886,9889} The fact that circulating levels of MPO have been shown to predict risks for major adverse cardiac events and that levels of MPO-derived chlorinated compounds are specific biomarkers for disease progression, has attracted considerable interest in the development of therapeutically useful MPO inhibitors.{16905} MPO also oxidizes a variety of substrates, including phenols and anilines, via the classic peroxidation cycle. The relative concentrations of chloride and the reducing substrate determine whether MPO uses hydrogen peroxide for chlorination or peroxidation. Assays based on measurement of chlorination activity are more specific for MPO than those based on peroxidase substrates because peroxidases generally do not produce hypochlorous acid. However, it is important that when screening for MPO inhibition that both the chlorination and peroxidation activities be tested. This determines whether the inhibitor specifically interferes with the chlorination and/or peroxidation cycle or whether the inhibitor simply acts as a scavenger for hypochlorous acid. Also, many reversible inhibitors act by diverting MPO from the chlorinating cycle to the peroxidase cycle. Cayman’s MPO Inhibitor Screening Assay provides convenient fluorescence-based methods for screening inhibitors to both the chlorination and peroxidation activities of MPO. The chlorination assay utilizes the non-fluorescent 2-[6-(4-aminophenoxy)-3-oxo-3H-xanthen-9-yl]-benzoic acid (APF), which is selectively cleaved by hypochlorite (-OCl) to yield the highly fluorescent compound fluorescein.{11242} Fluorescein fluorescence is analyzed with an excitation wavelength of 480-495 nm and an emission wavelength of 515-525 nm. The peroxidation assay utilizes the peroxidase component of MPO. The reaction between hydrogen peroxide and ADHP (10-acetyl-3,7-dihydroxyphenoxazine) produces the highly fluorescent compound resorufin. Resorufin fluorescence is analyzed with an excitation wavelength of 530-540 nm and an emission wavelength of 585-595 nm.

  • N6-Methyladenosine (m6A) is an abundant modification found in mRNA, tRNA, snRNA, as well as long non-coding RNA, in all species. RNA adenosine methylation is catalyzed by a multicomponent complex composed of METTL3/MT-A70, METTL14, and WTAP in mammals. METTL3 and METTL14 are responsible for the methyltransferase activity of the complex, and WTAP mediates substrate recruitment.{30057} The process shares similarities to histone methylation in that the modification is installed by m6A methylation “writers”, detected by methylation-specific “readers”, and can be reversed by demethylation “erasers”. The m6A modification has been shown to be conserved in the vicinity of stop codons and the 3’-untranslated region of specific mouse and human mRNAs.{25677} The process of regulating m6A modifications in mammalian mRNA has been linked to disease, where fat mass and obesity-associated (FTO) has been reported to be an obesity risk gene.{25677} FTO is an m6A demethylase and polymorphisms that result in increased FTO expression are associated with increased body mass and risk of obesity. Cayman’s N6-Methyladenosine Monoclonal Antibody (Clone 17-3-4-1) can be used for dot blot, ELISA, and immunoprecipitation applications.

  • Nicotinamide adenine dinucleotide (NAD) exists in an oxidized form, NAD+, as well as a reduced form, NADH. NAD, the main free form in cells, functions in modulating cellular redox status and by controlling signaling and transcriptional events, making it an important cofactor when investigating normal cellular function. Cayman’s NAD/NADH Cell-Based Assay Kit provides a colorimetric method for measuring intracellular NAD+ and NADH in cultured cells. In this assay, NAD+ found in cell samples is reduced to NADH by alcohol dehydrogenase during the oxidation of ethanol to acetaldehyde. The newly formed and the existing NADH found in the samples is then oxidized resulting in the reduction of a tetrazolium salt substrate (WST-1) to a highly-colored formazan which absorbs at 450 nm. The amount of formazan produced is proportional to the amount of total NAD in the cell lysate and can be used as an indicator of the total cellular NAD concentration.

  • Cayman’s NF-κB (p65) Transcription Factor Assay is a non-radioactive, sensitive method for detecting specific transcription factor DNA binding activity in nuclear extracts and whole cell lysates. A 96-well enzyme-linked immunosorbent assay (ELISA) replaces the cumbersome radioactive electrophoretic mobility shift assay (EMSA). A specific double stranded DNA (dsDNA) sequence containing the NF-κB response element is immobilized to the wells of a 96-well plate. NF-κB contained in a nuclear extract, binds specifically to the NF-κB response element. NF-κB (p65) is detected by addition of specific primary antibody directed against NF-κB (p65). A secondary antibody conjugated to HRP is added to provide a sensitive colorimetric readout at 450 nm. Cayman’s NF-κB (p65) Transcription Factor Assay detects human NF-κB (p65). It will not cross-react with NF-κB (p50).

  • The Cayman Chemical Nitrate/Nitrite Assay Kit provides an accurate and convenient method for measurement of total nitrate/nitrite concentration in a simple two-step process. The first step is the conversion of nitrate to nitrite utilizing nitrate reductase. The second step is the addition of the Griess Reagents which convert nitrite into a deep purple azo compound. Photometric measurement of the absorbance due to this azo chromophore accurately determines nitrite concentration. This kit can be used to measure nitrate and nitrite in plasma/serum, urine, tissue culture media, and tissue homogenates. However, it cannot be used to analyze nitrate and nitrite from an in vitro assay of nitric oxide synthase (NOS) in which excess NADPH has been added. For these assays a second method (LDH method) is utilized and is available from Cayman Chemical in a 96 well plate format (Item No. 760871).

  • NADPH is an essential cofactor for the function of the NOS enzyme. Unfortunately, NADPH interferes with the chemistry of the Griess reagents, which are the most commonly used reagents for nitrite detection. There are two ways to get around this limitation. Vanishingly small amounts of NADPH can be used, in conjunction with a catalytic system for recycling the spent NADP+ back to NADPH. This is the system used in Cayman’s first Nitrate/Nitrite Colorimetric Assay Kit (Item No. 780001). It works well for the analysis of fluids such as plasma and urine, and is also available in a high sensitivity fluorometric version (Item No. 780051) for the detection of low levels of nitrate and nitrite. However, this method cannot be used to analyze nitrate and nitrite from an in vitro NOS assay in which excess NADPH has been added. The second way to handle the NADPH interference problem is to go ahead and use an excess of NADPH. An additional step is added to the protocol to remove the excess NADPH. This is the avenue we have taken in the development of this nitrate/nitrite assay kit. This kit uses Lactate Dehydrogenase (LDH) to oxidize the excess NADPH. The kit is particularly well suited to measurements of NOS activity in vitro. High throughput screening applications using recombinant nitric oxide synthase (NOS) preparations can be quickly and accurately assayed with the LDH method kit. Each kit contains assay buffer, nitrate reductase, cofactors preparation, nitrate standard, lactate dehydrogenase, Griess Reagent R1, Griess Reagent R2, a 96 well plate, and complete instructions.

  • Nitric Oxide (NO) is produced in trace quantities by neurons, endothelial cells, platelets, and neutrophils in response to homeostatic stimuli. This NO is scavenged rapidly (t½ = 4 s) and acts in a paracrine fashion to transduce cellular signals. NO interacts with the HEME prosthetic group of guanylate cyclase, activating the enzyme and leading to increased cGMP levels. Other cells (macrophages, fibroblasts, and hepatocytes) also produce NO in micromolar concentrations in response to inflammatory or mitogenic stimuli. These very high levels of NO lead to the formation of peroxynitrite, destruction of iron-sulphur clusters, thiol nitrosation, and nitration of protein tyrosine residues. Thus, the amount of NO produced in different biological systems can vary over several orders of magnitude and its subsequent chemical reactivity is diverse. The final products of NO in vivo are nitrite (NO2-) and nitrate (NO3-). Relative proportions of NO2- and NO3- within a sample are variable and cannot be predicted with certainty. Therefore, the best index of total NO production is the sum of both of these products. Cayman Chemical’s Nitrate/Nitrite Fluorometric Assay Kit provides a convenient method for the quantitation of low levels of NO2- and NO3- in biological samples (particularly tissue culture medium). Previously undetectable concentrations of nitrate/nitrite in a variety of samples can be accurately quantitated using this kit as it extends the lower limit of detection by 20-fold over our popular colorimetric version. The minimum detectable quantity of NO2/NO3 is ~50 nM.

  • The ion channels activated by glutamate are typically divided into two classes. Glutamate receptors that are activated by kainate and α-amino-3-hydroxy-5-methyl-4-isoxalone propionic acid (AMPA) are known as kainate/AMPA receptors (K/AMPAR). Those that are sensitive to Nmethyl- D-aspartate (NMDA) are designated NMDA receptors (NMDAR). The NMDAR plays an essential role in memory, neuronal development and it has also been implicated in several disorders of the central nervous system including Alzheimer’s, epilepsy and ischemic neuronal cell death. The NMDA receptor is also one of the principal molecular targets for alcohol in the CNS. The NMDAR is also potentiated by protein phosphorylation. The rat NMDAR1 (NR1) was the first subunit of the NMDAR to be cloned. The NR1 protein can form NMDA activated channels when expressed in Xenopus oocytes but the currents in such channels are much smaller than those seen in situ. Channels with more physiological characteristics are produced when the NR1-subunit is combined with one or more of the NMDAR2 (NR2 A-D) subunits.

  • Present in nature in the form of iodide and iodate, iodine is a solid halogen at normal temperature. It is used in medicine, in the pharmaceutical and food industry. Food is the principal daily supply of iodide in human body.{35362} Iodide is important in basal metabolism and permits temperature regulation, intellectual development for children, muscular development, normal heart function and growth of skeleton. Iodide transport is the basis for an emerging approach of selective cancer cell destruction.{35363,35364} Iodide uptake from blood into thyroid follicular cells is the first step in the biosynthesis of thyroid hormones T4 and T3, known to regulate many essential biological processes.{35365,35366}Thyroid hormones are indispensable for body development. This transport is mediated by NIS (sodium iodide symporter), an intrinsic membrane glycoprotein located in the basolateral membrane of thyrocytes. Since the discovery of NIS, thorough biochemical analysis has elucidated the mechanism of basolateral iodide transport and revealed the key role of NIS in thyroid diseases such as thyroid cancer, autoimmune disease, and congenital hypothyroidism.{35367} If rate is not in the normal proportion, some diseases can be developed as underactive thyroid if the rate is too down or overactive thyroid if the rate is too up. Other diseases exist as chronic thyroiditis of Hashimoto or cancer of the thyroid gland.{35368} Iodide deficiency is at origins of many thyroid metabolism disorders, this is why it is important to control rate of iodide to prevent all of these diseases. This Iodide Assay is based on the oxido-reduction reaction: cerium(IV) is reduced by arsenic(III). The reduction of yellow (420 nm) cerium(IV) to colorless cerium(III) by arsenic(III) proceeds very slowly but traces of iodide strongly accelerate this reaction with the rate being directly proportional to iodide concentration. For a given time, decay is inversely proportional to iodide concentration in well. This method is simple and nonradioactive, and as such it can be used widely.[Bertin Catalog No. D05076.96]

The antibody preferentially recognizes polyubiquitinated Nrf2 at 90 kDa from human, mouse, and rat samples.

  • Nuclear factor erythroid 2-related factor 2 (Nrf2) is a basic leucine zipper transcription factor encoded by NFE2L2 in humans that regulates the cellular antioxidant response.{53865} It is a 605-amino acid protein comprised of seven highly conserved Nrf2-ECH (Neh) homology domains.{53866,53867} Nrf2 contains a large central domain that recruits transcriptional co-activators, mediates heterodimerization with the transcription factor Maf, and can be phosphorylated by GSK3 or the ubiquitin ligase adapter protein β-TrCP.{53867,53868} The Nrf2 central domain is flanked by an N-terminal Neh2 domain that binds the negative regulator Kelch-like ECH-associated protein 1 (Keap1; Item No. 32035) and a C-terminal Neh3 domain that is required for transactivation.{53867} Nrf2 is ubiquitously expressed and, under homeostatic conditions, associates with Keap1 in the cytoplasm, preventing Nrf2 nuclear translocation and promoting its ubiquitination and proteasomal degradation.{53866,53869} In the presence of xenobiotic electrophiles or oxidants, Keap1 releases Nrf2 which translocates to the nucleus, dimerizes with Maf, and induces the expression of a variety of cytoprotective genes that have antioxidant, anti-inflammatory, and metabolic functions.{53865,53870,53745} Nrf2 siRNA knockdown increases DNA-crosslinking and apoptosis induced by cisplatin (Item No. 13119) in A549 cancer cells, indicating that Nrf2 contributes to chemoresistance.{53871} Tumor Nrf2 levels are increased in patients with non-small cell lung cancer (NSCLC) and this increase is associated with poor overall survival.{53872} Cayman’s Nrf2 (N-Term) Polyclonal Antibody can be used for flow cytometry (FC), immunocytochemistry (ICC), and Western blot (WB) applications. The antibody recognizes native and polyubiquitinated Nrf2 at 67 and 90 kDa, respectively, from human, mouse, and rat samples.

  • Nuclear factor E2-related factor 2 (Nrf2) is a transcription factor that plays a key role in maintaining redox homeostasis via its interaction with a cysteine-rich protein Kelch-like ECH-associated protein 1 (Keap1). In resting cells, Nrf2 and Keap1 form a tight complex, which is targeted for degradation by proteasomes. Under oxidative stress, Nrf2 is released from the Nrf2/Keap1 complex and translocates to the nucleus where it is able to induce the expression of a battery of genes encoding diverse cytoprotective proteins, including antioxidative enzymes, anti-inflammatory mediators, and proteasomes. Cayman’s Nrf2 Transcription Factor Assay is a non-radioactive, colorimetric method for detecting specific transcription factor DNA binding activity in nuclear extracts. A specific double stranded DNA (dsDNA) sequence containing the Nrf2 response element is immobilized onto the wells of a 96-well plate. Nrf2 contained in nuclear extract samples will bind specifically to the Nrf2 response element and can be detected by addition of a specific Nrf2 antibody and a secondary antibody conjugated to HRP.

  • Obestatin is an amidated peptide of 23 amino-acids with an alpha-helical secondary conformation. It was first isolated from rat stomach in 2005. Obestatin is a preproghrelin-derived peptide produced by many tissues or organs, including the stomach, pancreas, adipose tissue, skeletal muscle, and heart. Obestatin was originally identified as an anorexigenic peptide that  reduces food intake and body weight by opposing the actions of ghrelin. It has also been considered to be an antidiabetic peptide that positively influences glucose and lipid metabolism. It may also play a role in the regulation of blood pressure as its plasma concentration increases in hypertensive patients. Obestatin may also have a role in the regulation of anxiety and memory improvement. [Bertin Catalog No. A05036]

  • Octamer-binding transcription factor 4 (Oct4) is an essential regulator of embryonic stem cell pluripotency and used as a marker for undifferentiated cells. It also plays a role in gene expression, DNA repair and/or replication, signal transduction and tumorigenesis. Cayman’s Oct4 Transcription Factor Assay is a non-radioactive, sensitive method for detecting specific transcription factor-DNA binding activity in nuclear extracts. A 96-well enzyme-linked immunosorbent assay (ELISA) replaces the cumbersome radioactive electrophoretic mobility shift assay (EMSA). A specific double-stranded DNA (dsDNA) sequence containing the Oct4 response element is immobilized onto the wells of a 96-well plate. Oct4, contained in a nuclear extract, binds specifically to the Oct4 response element. Oct4 is detected by the addition of a specific primary antibody directed against Oct4. A secondary antibody conjugated to HRP is added to provide a sensitive colorimetric readout at 450 nm.

  • Oligodendrocyte lineage transcription factor 1 (Olig1) is a basic helix-loop-helix transcription factor that promotes the formation and maturation of oligodendrocytes.{55117} It is expressed in the spinal cord and neuroepithelium of the ventral forebrain, colocalizing with the oligodendrocyte precursor markers Sox10 and Pdgfra. Olig1 is localized to the nucleus at the embryonic stage and is translocated to the cytoplasm after birth.{55118} However, Olig1 is translocated back to the nucleus of oligodendrocyte precursors following a demyelinating injury. Olig1-/- mice exhibit delayed, but not impaired, spinal cord oligodendrocyte differentiation and maturation, indicating that Olig1 is non-essential to oligodendrocyte differentiation.{55119} Olig1 knockdown delays mean disease onset and reduces disease severity in a mouse model of myelin oligodendrocyte glycoprotein-induced experimental autoimmune encephalomyelitis.{55120} Cayman’s Olig1 Polyclonal Antibody can be used for immunocytochemistry (ICC), immunohistochemistry (IHC), immunoprecipitation (IP), and Western blot (WB) applications. The antibody recognizes Olig1 at approximately 27 kDa from human, mouse, and rat samples.

  • Oligodendrocyte lineage transcription factor 2 (Olig2) is a basic helix-loop-helix transcription factor that is essential to the formation of oligodendrocytes and motor neurons in the spinal cord and somatic motor neurons in the hindbrain.{46965} It represses differentiation and sustains the replication-competent state of uncommitted progenitor cells to expand the progenitor cell pool during early development and promotes the cell fate decision to form oligodendrocyte progenitors and motor neurons in the spinal cord during late development. It also suppresses the formation of astrocytes in the spinal cord. Olig2 contains a triple serine motif at positions 10, 13, and 14 near its amino terminus that is subject to phosphorylation.{46966} Phosphorylation of Olig2 at this motif (phospho-Ser10,13,14) is developmentally regulated and decreases as Olig2+ progenitor cells mature into terminally differentiated oligodendrocytes. EB5 neurospheres expressing a triple phosphomimetic mutant of Olig2 induce more rapid tumor formation and decreased survival in mice compared with neurospheres expressing wild-type Olig2. Cayman’s Olig2 (Phospho-Ser10,13,14) Polyclonal Antibody can be used for Western blot (WB) applications. The antibody recognizes Olig2 (phospho-Ser10,13,14) at approximately 32 kDa from human, mouse, and rat samples.

  • Optineurin (OPTN) is an adapter protein with roles in autophagy, vesicular trafficking, and inflammatory responses to viral and bacterial pathogens.{47745} OPTN binds to ubiquitinated cargo via its ubiquitin-binding domain and targets them for autophagic degradation by recruiting LC3-expressing phagophore membranes via its LC3-interacting region. It is phosphorylated by TANK binding kinase 1 (TBK1), which increases the binding affinity of OPTN for polyubiquitinated mitochondria, promotes TBK1 activation and recruitment to the mitochondria, and permits the degradation of damaged mitochondria via PINK1/parkin-dependent mitophagy.{47746} OPTN regulates transferrin receptor trafficking and recycling by mediating the association between the membrane trafficking protein Rab8 and its activator TBC1D17.{47747} Mutation of the OPTN ubiquitin binding domain reduces LPS- and poly(I:C)-induced increases in IFN-β levels in bone marrow-derived macrophages (BMDMs).{47748} OPTN knockout increases mortality and reduces plasma levels of TNF-α and IL-6 in a mouse model of E. coli-induced peritonitis.{47749} Mutations in OPTN are associated with primary open angle glaucoma, amyotrophic lateral sclerosis (ALS), Paget’s disease, and Alzheimer’s disease.{47745,47750} Cayman’s Optineurin Monoclonal Antibody (Clone 8E12) can be used for immunocytochemistry applications.

  • The Orexin 1 Receptor (OX1R) may be an important therapeutic target for treatment of sleep disorders, obesity, emotional stress, and addiction. Cayman’s OX1R Reporter Assay Kit consists of a 96-well plate coated with a transfection complex containing DNA constructs for OX1R, a recombinant G-protein, and a cAMP response element regulated Secreted Alkaline Phosphatase (SEAP) reporter (OX1R Reverse Transfection Strip Plate). Cells grown on the transfection complex will express OX1R at the cell surface and the recombinant G-protein inside the cell. Binding of agonists to OX1R initiates a signal transduction cascade resulting in expression of SEAP which is secreted into the cell culture medium. Aliquots of culture medium are removed at time intervals beginning at about 16 hours and SEAP activity is measured following addition of a luminescence-based alkaline phosphatase substrate provided in the kit. The kit is easy to use and can be easily adapted to high throughput screening for therapeutic compounds regulating activation of OX1R. A known OX1R agonist, Orexin A, is included in the kit for use as a positive control. The kit provides sufficient reagent to measure SEAP activity at three time points, using the black plates provided.
