Quality Control

This peptide is manufactured under strict quality control protocols to ensure high purity and batch-to-batch consistency, essential for reliable research outcomes. Quality is verified through a comprehensive suite of analytical techniques including HPLC, MS, and amino acid analysis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every batch. Our processes are designed to meet the stringent requirements of research and pre-clinical development.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake. For extended storage under inert atmosphere, contact our technical team for specific recommendations.
