Quality Control

Our peptide products are manufactured under strict quality management systems. Each batch undergoes comprehensive analytical characterization to ensure identity, purity, and consistency. Certificates of Analysis (COA) are provided, detailing results from HPLC for purity, MS (Mass Spectrometry) for identity confirmation, and amino acid analysis. We support research and development with materials suitable for non-GMP applications, with purity levels typically exceeding 95%.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a freezer. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to minimize moisture uptake. For long-term storage, keep desiccated at -20°C.
