C-Peptide Mouse, Unlabeled, Clone: U8-424, BD

Description

• The U8-424 monoclonal antibody specifically binds to human, mouse, and rat C-Peptide, the connecting peptide that links the A- and B-chains in the proinsulin molecule
• The A- and B- chains and C-Peptide are encoded by the transcript of the INS gene and are produced by the β cells in the islets of Langerhans of the pancreas
• As the biosynthesis of insulin proceeds, the C-Peptide is cleaved from proinsulin to form the mature insulin hormone, which is composed of the A- and B-chains linked by 2 disulfide bonds
• Mature insulin and C-Peptide are stored i n granules in the β cells and are released to the blood in response to metabolic signals such as glucose, the amino acids arginine and leucine, and acetylcholine
• As a result, C-Peptide is released into the blood stream in an equimolar amount to insulin; the serum level of C- Peptide correlates with pancreatic β cell function and the amount of insulin being produced
• The expression of C-Peptide can be used to monitor the pancreatic differentiation of pluripotent stem cells
• Insulin is an evolutionarily conserved peptide hormone that binds to receptors on target cells (primarily adipose and muscle) to promote the absorption of glucose from the blood, thus regulating fat and carbohydrate metabolism
• C-Peptide itself binds to many cell types, independently of the insulin receptor, and initiates several intracellular signaling cascades.
