Quality Control

Our synthetic peptides are manufactured under strict cGMP-like conditions to ensure batch-to-batch consistency and traceability. Each lot undergoes rigorous analytical testing, including HPLC for purity and mass spectrometry (MS) for identity confirmation. Certificates of Analysis (COA) detailing purity, peptide content, and analytical results are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. For long-term storage, consider lyophilization and storage under an inert atmosphere to prevent oxidation and hydrolysis. Allow the vial to equilibrate to room temperature before opening to minimize moisture absorption.
