N-linked glycosylation is a highly regulated post-translational modification that is involved in protein folding and conformation, oligomerization, sorting, cell-cell interactions, and targeting of proteins to sub- or extra-cellular locations. It is initiated in the endoplastic reticulum with the transfer of a carbohydrate moiety to an asparagine residue within a specific amino acid consensus sequence and then further processed in the Golgi whereupon a mature glycoprotein is exported through the secretory machinery to the plasma membrane. Tunicamycin, a mixture of nucleoside antibiotics, is a specific inhibitor of N-linked glycoslylation that blocks the first step of glycoprotein synthesis thereby inducing protein unfolding. At 500 nM, it can impair the function of several receptor tyrosine kinases, including EGFR, ErbB2, ErbB3, and IGF-IR.{20913} Also at 500 nM, it radiosensitizes U251 glioma and BXPC3 pancreatic adenocarcinoma cells to chemotherapy.{20913} Tunicamycin impairs ALK phosphorylation and disrupts pro-survival signaling and cell viability in various neuroblastoma cell lines (IC50s range from 20 – 500 nM).{20914} Tunicamycin can also inhibit protein palmitoylation.{20912}

  • A powerful effector in both the TetR and revTetR transcriptional regulator systems

    Anhydrotetracycline (hydrochloride) – 250 mg

    The tetracycline repressor (TetR) is a transcriptional regulator which normally binds tightly to its palindromic tetO operator DNA, blocking gene expression.{17508} Tet causes the repressor to dissociate from the DNA, allowing transcription to occur. A novel reverse TetR (revTetR) requires tetracycline as a co-repressor to bind tetO and block transcription.{17509,17510} Anhydrotetracycline (hydrochloride) is a powerful effector in both the tetracycline repressor (TetR) and reverse TetR (revTetR) systems, binding the Tet repressor 35-fold more strongly than Tet.{17508,17511} Moreover, anhydrotetracycline poorly binds the 30S ribosomal subunit, compared to Tet,{17512} so it does not act as a general inhibitor of translation and is a poor antibiotic. Perhaps related to this, the concentration of anhydrotetracycline that inhibits eukaryotic cell growth is more than a 1,000-fold above the dose that alters transcription through TetR.{17508}

    PtdIns-(3,4,5)-P3-biotin (sodium salt) – 100 µg

    The PtdIn phosphates play an important role in the generation and transduction of intracellular signals.{8344,4096,14518} PtdIns-(3,4,5)-P3-biotin is an affinity probe which allows the PIP3 to be detected through an interaction with the biotin ligand. This design allows PtdIns-(3,4,5)-P3-biotin to serve as a general probe for any protein with a high affinity binding interaction with inositol-(3,4,5)-triphosphate phospholipids, such as phosphatidylinositol 3-kinase, PTEN, or PH-domain-containing proteins.
