  • The oxygen consumption rate (OCR) of cells is an important indicator of normal cellular function. It is used as a parameter to study mitochondrial function as well as a marker of factors triggering the switch from healthy oxidative phosphorylation to aerobic glycolysis in cancer cells. Oxygen consumption is traditionally measured by a cumbersome oxygen electrode, a specialized piece of equipment that typically yields low sample throughput. A Phosphorescent Oxygen Probe has proven to be useful in measuring oxygen consumption rates in whole cells. Cayman’s cell-based Oxygen Consumption Rate Assay Kit utilizes this newly developed phosphorescent oxygen probe to measure oxygen consumption rate in living cells. Antimycin A, an inhibitor of the mitochondrial electron transport chain, is included to be used as a positive control. Glucose oxidase is also included in the kit to be used as a reference for oxygen depletion. The kit is easy to use and can be easily adapted to high throughput screening for compounds which modulate oxygen consumption rate.

  • Cayman’s PAD1 Inhibitor Screening Assay Kit (AMC) provides a convenient method for screening human PAD1 inhibitors. This assay utilizes a fluorescent substrate (Z-Arg-AMC) consisting of an arginine residue, a carboxybenzyl group, and a fluorophore (7-amino-4-methylcoumarin, AMC).{31179} Acylation of AMC onto the arginine residue masks the fluorescence of the fluorophore. In the absence of PAD1, the substrate remains unaltered, allowing the developer to release free AMC. In the presence of PAD1, the arginine of the substrate is citrullinated, and while the reaction is quenched by the addition of developer, free AMC is not released. Fluorescence is analyzed with an excitation wavelength of 355-365 nm and an emission wavelength of 445-455 nm. The fluorescent signal is inversely proportional to the amount of citrullination by PAD1.

  • Platelet-activating factor (PAF) is a biologically active phospholipid synthesized by a variety of cells upon stimulation. PAF is converted to the biologically inactive lyso-PAF by the enzyme PAF acetylhydrolase (PAF-AH). Plasma PAF-AH is highly selective for phospholipids with very short acyl groups at the sn-2 position and is associated with lipoproteins.{2626} The Cayman Chemical PAF acetylhydrolase assay kit provides an accurate and convenient method for measurement of PAF-AH activity. The assay uses 2-thio PAF which serves as a substrate for PAF-AH.{3787} Upon hydrolysis of the acetyl thioester bond at the sn-2 position by PAF-AH, free thiols are detected using 5,5′-dithio-bis(2-nitrobenzoic acid) (DTNB; Ellman’s reagent). The dynamic range of the assay is only limited by the accuracy of the absorbance measurement. Most plate readers are linear to an absorbance of 1.2. The detection range of the assay is from 0.02 to 0.2 µmol/min/ml of PAF-AH activity which is equivalent to an absorbance increase of 0.01 to 0.1 per minute. Each kit contains assay buffer, DTNB, 2-thio PAF (substrate), human PAF-AH standard, a 96 well plate, and complete instructions.

Plasma PAF-AH is highly selective for phospholipids with very short acyl groups at the sn-2 position and is associated with lipoproteins.{2626} Recently, plasma PAF-AH has been linked to atherosclerosis and may be a positive risk factor for coronary heart disease in humans.{11455} The Cayman Chemical PAF Acetylhydrolase Inhibitor Screening Assay uses 2-thio PAF as a substrate for PAF-AH.{3787} Upon hydrolysis of the acetyl thioester bond at the sn-2 position by PAF-AH, free thiols are detected using 5,5′-dithio-bis-(2-nitrobenzoic acid) also known as DTNB or Ellman’s reagent. Cayman’s PAF-AH Inhibitor Screening assay includes human plasma PAF-AH and is a time saving tool for screening vast numbers of inhibitors.

  • The poly(ADP-ribose) polymerase (PARP) is involved in cell recovery from DNA damage, such as methylation of N3-adenine, which activates the base excision repair process. PARP is a 116 kDa nuclear chromatin-associated enzyme that is cleaved during apoptosis by caspase-3 into a 24 kDa fragment containing the DNA binding domain and an 89 kDa fragment containing the catalytic and automodification domains. The 24 kDa fragment irreversibly binds to DNA and may contribute to the irreversibility of apoptosis by blocking the access of DNA repair enzymes to DNA strand breaks.

  • Cayman’s PHLPP1 Polyclonal Antibody detects the carboxy-terminal amino acids within the PDZ-binding domain of both the PHLPP1 α and β isoforms. PHLPP2 shares partial identity with the domains of PHLPP1 however it has a unique PDZ-binding domain sequence. Protein kinase B/Akt is critical in regulating cell growth and death. Activation of a serine residue (Ser473) in a C-terminal hydrophobic motif of Akt is known to be linked to some of the most common human cancers. PHLPP1 and PHLPP2 dephosphorylate the hydrophobic motif of Akt and thus reduce Akt activity, resulting in a increase in the number of apoptotic cells.{13717} PHLPP1 levels are markedly reduced in several colon cancer and glioblastoma cell lines that have elevated Akt phosphorylation. Injection of a human glioblastoma cell line overexpressing PHLPP1 into mice reduced tumor size by nearly 70% compared with control animals. mRNA of PHLPP1 is ubiquitously expressed, with highest levels found in brain.{13717} Cayman’s PHLPP Polyclonal Antibody detects the enzyme at around 150 kDa (α isoform) and 200 kDa (β isoform) by western blot from various cell lines (THP-1) and tissues such as brain.

  • Protein phosphorylation is an important post-translational modification that serves many key functions to regulate a protein’s activity, localization, and protein-protein interactions. Phosphorylation is catalyzed by various specific protein kinases, which involves removing a phosphate group from ATP and covalently attaching it to a recipient protein that acts as a substrate. Most kinases act on both serine and threonine; others act on tyrosine, and a number (dual specificity kinases) act on all three. Because phosphorylation can occur at multiple sites on any given protein, it can therefore change the function or localization of that protein at any time.{17293} Changing the function of these proteins has been linked to a number of diseases, including cancer, diabetes, heart disease, inflammation, and neurological disorders.{17295,17296,17297}

  • Podoplanin is a mucin type-1 glycoprotein of 40-43. Podoplanin is expressed in many tumors and many normal cells, especially lymphatic epithelial cells and follicular DCs. It appears to serve as a ligand for CLEC-2. Podoplanin expression is positively correlated with tumors expressing greater invasive and metastatic potential. Podoplanin is directly involved in cell migration, aids metastases formation and tumor cell invasion of tissue.{19761,19762,19763} It has also been determined that podoplanin expression is induced through Src activation of Cas.{19760} Recently there are indications of podoplanin presence on Th17 cells.{19759} Initial studies below indicate the presence of podoplanin on a small but distinct population of CD4+ cells from human PBMC.

  • Podoplanin is a 43 kD type 1 transmembrane glycoprotein found on many tissues. Podoplanin appears to be differentially expressed by lymphatic endothelial cells but not blood vessel endothelial cells.{19761} Podoplanin has also been found to be expressed on a wide variety of tumors. It appears to be involved in lymphangioigenesis and promoting cell migration.{19764} Recently, there are indications of podoplanin presence on Th17 cells.{19759} In a murine EAE model for autoimmune disease it has been shown that Th17 cells migrate quickly to the CNS at EAE onset. Injection of antibody to podoplanin in mice also immunized with myelin antigen to induce EAE results in elevated numbers of Th17 cells in the CNS. Thus as in effecting migration of tumor cells, podoplanin may also promote migration of committed Th17 cells to sites of inflammation in autoimmune diseases.

  • Polyethylene glycols (PEGs) are synthetic and hydrophilic polymers.{57302,57303} They are linear or branched and contain a reactive end group, such as acrylate, methacrylate, dibenzocyclooctynol, or vinyl sulfonate, for covalent attachment to macromolecules or linkers. The opposite end group of PEGs is commonly a methyl group (methoxy PEG), however, hydroxy, amino, butoxy, and tert-butoxy end groups have also been used.{57302} PEGs are non-toxic and are commonly used to prolong the in vivo circulation time of pharmaceutical agents.{57303} Free PEGs are non-immunogenic but become immunogenic when conjugated to a drug delivery nanosystem (DDS) or a macromolecule.{57302} Immunogenicity of PEGs varies based on polymer length and branching, end group composition, and chemical nature of the PEG acceptor structure. Cayman’s Polyethylene Glycol Rabbit Monoclonal Antibody can be used for ELISA, immunohistochemistry (IHC), and Western blot (WB) applications. The antibody recognizes PEGs containing a methoxy end group.

  • Peroxisome Proliferator Activated Receptors (PPARs) are ligand-activated transcription factors belonging to the large superfamily of nuclear receptors.{7660,12196} They are activated by a variety of fatty acids and fatty acid derivatives such as prostaglandins and leukotrienes. PPARs play pivotal roles in the regulation of lipid metabolism and homeostasis and are important indirect as well as direct regulators of cellular insulin sensitivity.{10561} There are three major PPAR isotypes; PPARα, PPARγ, and PPARδ/β which all bind to PPAR responsive elements (PPRE’s) as heterodimers with RXR, another member of the nuclear receptor superfamily. PPARα primarily activates genes encoding proteins involved in fatty acid oxidation, while PPARγ primarily activates genes directly involved in lipogenic pathway and insulin signaling.{7660,8987,10011} Members of the PPAR family are important direct targets of many antidiabetic and hypolipidemic drugs.{6047} Cayman’s PPARα, δ, γ Complete 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).

  • Peroxisome proliferator-activated receptors (PPARs) are ligand activated nuclear receptors. Three PPAR subtypes have been identified: α, β (also called δ and NUC1), and γ. PPARγ is the most widely studied PPAR and exists in two protein isoforms (γ1 and γ2) due to use of an alternative promoter and alternative splicing.{12922} PPARγ is primarily expressed in adipose tissue and to a lesser extent in colon, the immune system, and the retina.{12196} PPARγ was first identified as a regulator of adipogenesis, but also plays an important role in cellular differentiation, insulin sensitization, atherosclerosis, and cancer. Ligands for PPARγ include fatty acids, arachidonic acid metabolites such as 15-deoxy-D12,14-PGJ2, as well as the thiazolidinedione class of compounds (TZD) which include pioglitazone and rosiglitazone.{12961} TZDs are potent, selective PPARγ agonists that lower the hyperglycemia, hyperinsulinemia, and hypertriglyceridemia found in type 2 diabetic subjects and are presently used as oral antidiabetic drugs.{7654,10857} The use of these synthetic ligands has increased the understanding of PPARγ’s mechanism of activation and subsequent biological effects. By increasing our understanding of PPARγ additional drug candidates may be identified. Cayman’s PPARγ Ligand Screening Assay Kit provides a convenient fluorescence polarization (FP)-based single step assay for screening PPARγ ligands. In this assay, a ligand of PPARγ was conjugated to fluorescein and is used as the displacement probe. Ligands, agonists, and antagonists of PPARγ will displace the fluorescent probe leading to a decrease in FP. The PPARγ Ligand Screening Assay Kit is a robust assay with a Z’ of 0.81 and has a dynamic range of greater than 120 mP units. The assay has been validated using known agonists/ligands of PPARγ (Arachidonic Acid, Rosiglitazone, Troglitazone, etc.) with IC50 values ranging from nanomolar to millimolar concentrations.

  • Progesterone, along with pregnenolone, is the biosynthetic precursor of all other steroid hormones. Progesterone is synthesized from cholesterol by the sequential action of desmolase in the mitochondria, which produces pregnenolone, followed by Δ4,5-isomerase in the outer mitochondrial membrane and smooth endoplasmic reticulum of steroid-secreting cells.{8458} The main function of progesterone is to prepare the uterine lining for implantation of a fertilized ovum and to maintain pregnancy. Measurement of serum or plasma progesterone levels are used as an index to monitor ovulation and investigate luteal function. Plasma concentrations of progesterone are approximately 0.2-0.8 ng/ml and 4-20 ng/ml during the follicular phase and luteal phase of the menstrual cycle, respectively.{8458} Salivary concentrations of progesterone are approximately 100-fold lower than those found in plasma.{1639}

  • There is accumulating evidence to suggest that progesterone plays an essential role in the regulation of growth and differentiation of mammary glands and thus may play a key role in breast cancer.{14655} The biological response to progesterone is mediated by two distinct forms of the human progesterone receptor (PR-A and PR-B forms). In most cell contexts, the B form functions as a transcriptional activator, whereas the A form functions as a transcriptional inhibitor of steroid hormones.{14653,14656} Recently it has been demonstrated that there is differential hormone dependent regulation of the phosphorylation of the A and B forms of the receptor.{14654} Treatment of T47D breast cancer cells with progestin agonist increases the phosphorylation of Ser190 and Ser294 with different kinetics. These phosphorylation events may differentially affect the transcriptional activity of the receptor.

  • Programmed cell death protein 4 (PDCD4) levels are elevated during apoptosis and absent in many cancer samples.{16340,16167} Loss of PDCD4 expression is an important event in cancer cell progression whereas the restoration of PDCD4 protein can lower metalloproteinase activity and possible metastasis.{16167,16166} The known isoforms of PDCD4 differ only at the N-terminial with isoform 1 comprised of 468 amino acids and isoform 2 comprised of 458 amino acids. Each isoform contains two MA-3 domains essential for binding of PDCD4 binding to eIF4A, thereby suppressing cell cycle regulation and growth factor production.{16167,16166,16345} This antibody is capable of detecting both PDCD4 isoforms. Additional protein modifications are possible and can explain the range of masses detected by immunoblotting (52-64 kDa).{16340} The molecular mechanisms of PDCD4 influence on tumor suppression are becoming known but warrant further research.{16167,16166,16168}

  • Prolactin is a polypeptide hormone synthesized and secreted by the anterior pituitary gland, placenta, decidua, and by various immune system cells, such as T cells, B cells, and NK cells. It has many functions, including stimulating mammary glands to produce milk (lactation), stimulating surfactant in the fetal lungs at the end of pregnancy, inducing immune tolerance of the fetus during pregnancy, as well as other immuno-regulatory and reproductive functions, and may also have a role in breast cancer development. Cayman’s human Prolactin ELISA Kit is an immunometric (i.e., sandwich) ELISA that can be used to measure prolactin within the range of 0.12-100 ng/ml. This assay offers specific and sensitive analysis of prolactin in human serum and plasma, and has not been validated for other types of samples.

  • Prolactin (PRL) is a pituitary hormone whose molecular weight is approximately 23000 Daltons. It is a single polypeptide chain composed of about 200 amino acid residues with three disulphide bonds. In mammals prolactin has been claimed to exert a wide range of different physiological effects. These include stimulation of mammary gland development and lactation, hair maturation, synergism with androgen in male sex accessory growth and maintenance and secretion of corpus luteum. PRL is predominantly under inhibitory control by the hypothalamus. Stimulation of prolactin release can be mediated by dopamine and thyrotrophin-releasing hormone(TRH).

  • Prostaglandin D2 (PGD2) is synthesized by hematopoietic-type PGD-synthase (H-PGDS) in mast cells and is released in large quantities during allergic and asthmatic anaphylaxis. H-PGDS is therefore a key target for development of selective, potent inhibitors for therapeutic use against these diseases. Cayman’s H-PGDS FP-Based Inhibitor Screening Assay Kit – Green provides a rapid, accurate assay for screening H-PGDS inhibitors. In this assay, a H-PGDS inhibitor-fluorescein conjugate serves as a specific fluorescent probe for the enzyme. Displacement of the probe by any unlabeled H-PGDS inhibitor leads to a decrease in the fluorescence polarization (FP) state of the probe, providing a direct signal for binding of the inhibitor to the active site of the enzyme. This assay is robust (Z’ of 0.75) and eliminates the need for the traditional multistep assay that requires the use of highly unstable PGH2. The assay has been validated using several known inhibitors of H-PGDS with IC50 values ranging from nanomolar to millimolar concentrations.

  • Prostaglandin D synthase (PGDS) catalyzes the isomerization of PGH2 to produce PGD2, a potent lipid mediator involved in sleep regulation, nociception, platelet aggregation, and allergic and inflammatory responses. Lipocalin-type PGDS (a.k.a. β-trace) is a homodimer with each subunit ranging in size from 20-31 kDa, depending on the extent of glycosylation. L-PGDS has two functions: it catalyzes the conversion of PGH2 to PGD2 and acts as a carrier protein for lipid-like molecules (i.e., retinoids and thyroid hormones).{13130} L-PGDS is present in a variety of body fluids including cerebrospinal fluid, seminal fluid, and plasma. Cayman’s L-PGDS (human) ELISA is an immunometric (i.e., sandwich) ELISA with a standard curve ranging from 1.56-100 ng/ml and a limit of detection of 1.56 ng/ml. Inter- and intra-assay CV’s of less than 15% may be achieved at most concentrations. This assay has been validated using cerebrospinal fluid which contains approximately 12-30 µg/ml of L-PGDS.
