Quality Control

Our peptide products are manufactured under strict quality management systems. Each batch undergoes comprehensive analytical characterization, including HPLC for purity and MS for identity confirmation, to ensure consistency and reliability for critical research applications. We provide full traceability and Certificates of Analysis (COA) detailing purity, content, and analytical data. Specifications can be aligned with research-grade or cGMP standards upon request.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store desiccated at -20°C or below. This product is hygroscopic (moisture-sensitive) and should be allowed to equilibrate to room temperature in a dry environment before opening to prevent condensation. Aliquot into single-use vials to minimize repeated freeze-thaw cycles and exposure to air.
