Quality Control

Our Tyrosyl-Seryl(o-tert-Butyl)-Glycyl-Phenylalanyl-Leucyl-Threonine is produced under controlled conditions to ensure high purity and batch-to-batch consistency, suitable for research applications. Each lot undergoes rigorous analytical testing, including HPLC for purity and MS for identity confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, related substances, and residual solvents is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This material is hygroscopic (moisture-sensitive); allow the sealed vial to equilibrate to room temperature before opening to minimize moisture uptake. For short-term use, store desiccated at 2-8°C.
