Quality Control

Our H-Tyrosyl-Glutaminyl-Glutaminyl-Glutaminyl-Hydroxyproline is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, MS for identity confirmation, and chiral analysis to ensure stereochemical integrity. Certificates of Analysis (COA) detailing all specifications are provided to guarantee reproducible quality and compliance with research-grade standards.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. Due to its hygroscopic nature, allow the sealed vial to equilibrate to room temperature before opening to minimize moisture uptake. For long-term storage, consider under an inert atmosphere.
