| PEP-CP001 | Rat C-Peptide 1 is a 33-residue linker peptide cleaved from proinsulin, specific secreted biomarker of pancreatic β-cells released equimolarly with insulin, core reagent for rat diabetic model islet function, glycometabolism & insulin secretion pathway research | Rat C-Peptide 1 (encoded by Ins2 gene) is the intermediate connecting segment excised during proinsulin post-translational maturation. Upon glucose stimulation of pancreatic β-cells, C-peptide 1 is co-secreted into circulation at an equal molar ratio with insulin. Its longer serum half-life makes it a superior detectable biomarker to evaluate rat islet reserve, β-cell injury, type 1/type 2 diabetes and insulin resistance. Additional physiological effects: improves microvascular perfusion, inhibits endothelial apoptosis, regulates renal microcirculation and alleviates diabetic nephropathy lesions. It has no binding affinity to insulin receptor and exhibits no hypoglycemic activity, only serving as a tracking tool for pancreatic endocrine secretion. Widely applied in rat diabetic pharmacology, pancreatic β-cell biology, glucose & lipid metabolism, proinsulin processing mechanism, diabetic complications, endocrine biomarker assay methodology research | Rat diabetic pharmacology, Pancreatic β-cell biology, Glucose & lipid metabolic pathway, Proinsulin cleavage processing, Diabetic nephropathy model, Endocrine biomarker development, Insulin secretion regulation, Animal metabolic pathology | No high-affinity specific receptor; Proinsulin processing proteases (PC1/3, PC2) |
