Quality Control

Our synthetic peptides 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 advanced techniques such as HPLC for purity, mass spectrometry (MS) for identity confirmation, and amino acid analysis (AAA). We support compliance with cGMP and ISO 9001 standards for research and development materials.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. For long-term storage, lyophilized material is recommended. The product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature before opening to prevent condensation.
