Description

Insulin B (9-30) is a defined synthetic peptide fragment corresponding to the B-chain sequence of insulin. This high-purity reference standard is critical for analytical research, method development, and quality control in the biopharmaceutical sector. It is primarily utilized by research institutions, diagnostic kit manufacturers, and pharmaceutical companies engaged in peptide synthesis, metabolic studies, and the development of insulin analogs.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the quantification and identification of insulin and its derivatives in drug products via HPLC, LC-MS, or immunoassays.
• Biochemical Research: Serves as a key reagent in metabolic pathway studies, receptor binding assays, and investigations into the structure-activity relationship (SAR) of insulin.
• Diagnostic Development: Employed in the calibration and validation of diagnostic kits and assays designed to measure insulin levels in clinical samples.
• Peptide Synthesis & Mapping: Acts as a building block or a digestion marker for peptide synthesis and for creating peptide maps to characterize larger insulin-related proteins.
• Quality Control (QC) Testing: Essential for in-process testing and final release testing of therapeutic insulin products to ensure identity, purity, and potency.
