Quality Control

Our peptide products are manufactured under strict quality management systems. Each batch of H-Ala-Ser-Gln-Phe-Glu-Thr-Ser-Oh undergoes comprehensive analytical testing, including HPLC for purity verification, mass spectrometry (MS) for identity confirmation, and amino acid analysis (AAA). Certificates of Analysis (COA) detailing all specifications are provided with every shipment to ensure traceability and compliance with your research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. For long-term storage, the product should be kept desiccated at -20°C. Allow the vial to equilibrate to room temperature before opening to minimize moisture absorption. This material is hygroscopic (moisture-sensitive).
