Product Overview

Human C Peptide is a 31-amino acid connecting peptide that plays a central role in insulin biosynthesis. It is cleaved from proinsulin during the maturation of insulin within pancreatic beta cells. In the research setting, Human C Peptide has become a valuable biochemical tool for scientists investigating beta-cell function, insulin secretion dynamics, and metabolic regulation. Direct Anti Peptide offers this compound in a sealed, pharmaceutical-grade glass vial as a lyophilized powder, optimized for laboratory stability and precision handling. Researchers can buy Human C Peptide online from our store with confidence in product integrity, documentation, and rapid fulfillment.

Peptide Structure & Amino Acid Sequence

Human C Peptide consists of a defined 31-amino acid sequence connecting the A and B chains of proinsulin. Its sequence is: Glu-Ala-Glu-Asp-Leu-Gln-Val-Gly-Gln-Val-Glu-Leu-Gly-Gly-Gly-Pro-Gly-Ala-Gly-Ser-Leu-Gln-Pro-Leu-Ala-Leu-Glu-Gly-Ser-Leu-Gln. This sequence is species-specific and corresponds precisely to the endogenous human form, making it the preferred reference standard for research requiring physiological relevance and biological specificity. The peptide’s molecular architecture supports its use as an analytical reference, a competitive inhibitor in binding assays, and a structural comparator in biochemical studies.

Purity & Analytical Verification (HPLC & MS)

Every batch of Human C Peptide supplied by Direct Anti Peptide is verified to ≥98% purity using high-performance liquid chromatography (HPLC). Mass spectrometry (MS) confirmation is applied to validate the molecular weight and confirm peptide identity. These dual analytical methods ensure that each vial contains a single, well-characterized compound free from significant impurities, truncated sequences, or synthesis by-products. Researchers conducting quantitative assays or comparative studies can rely on this analytical rigor to maintain experimental reproducibility and data integrity.

Quality Control & Lyophilization Integrity

Direct Anti Peptide applies strict quality control protocols at every stage of production and packaging. The lyophilization process is performed under controlled conditions to ensure uniform powder morphology, consistent residual moisture levels, and complete preservation of peptide structure. Each vial is sealed under inert atmosphere conditions to prevent oxidation and contamination. Lot-specific certificates of analysis (CoA) are available upon request, providing full traceability of purity data, analytical results, and batch identification for regulatory and laboratory record-keeping purposes.

Safety, Handling & Laboratory Precautions

Human C Peptide is supplied exclusively for use by trained research professionals operating within certified laboratory environments. Standard laboratory safety protocols must be observed at all times. Researchers should wear appropriate personal protective equipment, including gloves, eye protection, and lab coats, when handling this compound. This product has not been evaluated for safety in biological systems and must not be administered to humans or animals under any circumstances. Disposal must comply with applicable institutional and regulatory waste management guidelines.

Reconstitution, Packaging & Storage

Human C Peptide is supplied as a lyophilized powder in a sterile, pharmaceutical-grade glass vial. For laboratory reconstitution, researchers should follow validated protocols appropriate to their specific assay requirements, using only research-grade solvents or buffers. Upon reconstitution, aliquoting and immediate use or cryogenic storage is recommended to minimize degradation. The lyophilized product should be stored at -20°C or below, away from light and moisture. When stored under these recommended conditions, the product maintains stability for extended periods without significant loss of purity or structural integrity.

Intended Research Use & Market Positioning

Human C Peptide is widely used in academic, pharmaceutical, and biotechnology research contexts. Key research applications include the assessment of pancreatic beta-cell function, investigation of insulin biosynthesis pathways, development and validation of immunoassays, and exploration of metabolic disorders including type 1 and type 2 diabetes models.
