Quality Control & Manufacturing Standards

• Purity Verification: High-performance liquid chromatography (HPLC) confirms a minimum purity of ≥98%, minimizing contaminants that could interfere with experimental results.
• Identity Testing: Mass spectrometry (MS) and amino acid sequencing validate the peptide’s molecular structure and sequence, ensuring consistency across batches.
• Solubility and Stability Testing: Accelerated stability studies confirm the peptide’s solubility in aqueous solutions and resistance to degradation under typical storage conditions.
• Documentation: Each batch is accompanied by a Certificate of Analysis (COA), detailing purity, molecular weight, and stability metrics to meet institutional and regulatory requirements for research materials.

Packaging, Handling & Storage Guidelines

• Packaging: The polypeptide is supplied in sterile, airtight vials containing lyophilized powder, clearly labeled with product name, batch number, purity grade, and expiration date. Custom packaging options are available for bulk research orders.
• Handling: Standard laboratory safety protocols must be followed when handling the peptide, including the use of sterile gloves and work in a clean, controlled environment to prevent contamination. The lyophilized powder should be reconstituted with sterile water or PBS buffer immediately before use, following specific experimental protocols.
• Storage:
  • Dry Powder: Store at -20°C in a dark, sealed container to protect from light and moisture. Under these conditions, the product has a shelf life of 24 months from the date of manufacture.
  • Reconstituted Solution: After dissolution, store at 2–8°C and use within 7–14 days. Repeated freeze-thaw cycles must be avoided, as these can compromise the peptide’s structure and biological activity.
