CST, 92931SF, GUCY2C (E6I2U) Rabbit Monoclonal Antibody (BSA and Azide Free)

Monoclonal Antibody for studying GUCY2C. Validated for Western Blotting,Immunohistochemistry (Paraffin). Highly specific and rigorously validated in-house, GUCY2C (E6I2U) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #92931) is ready to ship. Product Usage Information This product is the carrier free version of product #37517. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol. This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN or CUT&Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us . Optimal dilutions/concentrations should be determined by the end user. BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity. Formulation Supplied in 1X PBS (10 mM Na 2 HPO 4 , 3 mM KCl, 2 mM KH 2 PO 4 , and 140 mM NaCl (pH 7.8)). BSA and Azide Free. For standard formulation of this product see product # 37517 Storage Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance. Specificity / Sensitivity GUCY2C (E6I2U) Rabbit Monoclonal Antibody (BSA and Azide Free) recognizes endogenous levels of total GUCY2C protein. Non-specific staining was observed in acinar cells of the salivary gland and keratinized epithelium of the skin by immunohistochemistry. Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Lys1046 of human GUCY2C protein. Background Guanylyl cyclase C (GUCY2C) is a type I transmembrane glycoprotein whose expression in normal tissue is largely restricted to the apical membranes of polarized epithelial cells of the intestine (1,2). The guanylyl cyclase activity within the intracellular domain of GUCY2C is activated by binding exogenous bacterial enterotoxins and the endogenous peptide hormone agonists, guanylin and uroguanylin, which facilitates production of the second messenger cGMP (3-5). GUCY2C signaling plays a critical role in regulating the metabolism, proliferation, and differentiation of intestinal epithelial cells. These processes are critical for epithelial barrier renewal, water, and ion balance (6-8). Research studies have shown that the GUCY2C signaling axis functions to suppress intestinal tumorigenesis, in part, by restraining AKT activity (9,10). Lesions in the GUCY2C signaling axis that frequently contribute to cellular transformation are associated with a loss of expression of its endogenous ligands, which promotes a compensatory increase in GUCY2C expression. Indeed, GUCY2C expression is maintained in a high percentage of primary and metastatic human colorectal tumors, which has raised interest in therapeutically targeting this receptor (11,12).
