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 HPLC for purity, mass spectrometry (MS) for identity confirmation, and amino acid analysis (AAA). We adhere to relevant guidelines for research-grade biochemicals to guarantee reliable performance in your critical applications.

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). For long-term storage, consider desiccation and storage under inert atmosphere. Allow the vial to equilibrate to room temperature before opening to minimize moisture uptake.
