Description

Proinsulin C-Peptide (31-63) (Porcine) is a defined fragment of the connecting peptide region of porcine proinsulin, a critical molecule in insulin biosynthesis research. This high-purity peptide is essential for scientific studies investigating proinsulin processing, C-peptide physiology, and the development of diagnostic assays. It serves as a vital reference standard and research reagent for pharmaceutical R&D, academic institutions, and diagnostic manufacturers focused on metabolic disease research and biopharmaceutical development.

Application

• Biochemical Research: Used as a key reference standard in studies of insulin biosynthesis, processing, and secretion mechanisms.
• Diagnostic Development: Serves as a critical antigen and calibrator in the development and validation of immunoassays (e.g., ELISA, RIA) for measuring C-peptide levels.
• Pharmaceutical R&D: Employed in metabolic disease research, particularly in diabetes, to study C-peptide's potential biological activities and therapeutic effects.
• Quality Control: Acts as a system suitability standard in analytical methods (HPLC, MS) for related peptide and insulin product characterization.
• Cell Biology Studies: Utilized in in vitro experiments to investigate receptor interactions and cellular signaling pathways associated with C-peptide.
