Description

C-Peptide (Human) CAS NO 33017-11-7 is a 31-amino acid polypeptide that is cleaved from proinsulin during the production of insulin. This compound serves as a critical biomarker for endogenous insulin secretion, providing valuable insights into pancreatic β-cell function. It is essential for researchers and manufacturers in the fields of diabetes research, diagnostic assay development, and pharmaceutical quality control.

Application

• Diabetes Research & Biomarker Studies: Used as a standard and reagent in clinical and preclinical research to measure C-peptide levels, which correlate with insulin production.
• In Vitro Diagnostic (IVD) Manufacturing: A key component in the calibration and quality control of immunoassay kits for diabetes monitoring and management.
• Metabolic Disorder Investigations: Applied in studies exploring insulin resistance, β-cell mass, and the pathophysiology of type 1 and type 2 diabetes.
• Pharmaceutical Reference Standard: Serves as a high-purity reference material for the analysis and quality assurance of insulin and related therapeutic products.
• Cell Biology & Physiology: Utilized in experiments to study proinsulin processing, peptide hormone kinetics, and cellular signaling pathways.
