Quality Control

Our Desamino-Tyrosyl-Phenylalanyl-Leucyl-Phenylalanyl-Glutaminyl-Prolyl-Glutaminyl-Argininamide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, mass spectrometry (MS) for identity confirmation, and amino acid analysis (AAA). We provide full traceability and Certificates of Analysis (COA) are available for all shipments, detailing purity, related substances, and residual solvent levels where applicable.

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 extended storage, consider desiccation.
