Quality Control

Our synthetic peptides are manufactured under strict cGMP-like conditions to ensure the highest standards of purity and consistency. Every batch undergoes comprehensive analytical characterization, including HPLC for purity, mass spectrometry (MS) for identity confirmation, and amino acid analysis (AAA). Certificates of Analysis (COA) detailing all specifications and test results are available 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). Allow the vial to reach room temperature in a dry environment before opening to minimize moisture uptake.
