Quality Control

Our Gastrin I Fragment Human 1-13 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 upon request, detailing purity, peptide content, and analytical results.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. For long-term storage, lyophilized powder is recommended. The product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature before opening to minimize moisture uptake.
