Quality Control

Our 7-Ornithine-Tyrocidine A is produced under controlled conditions to ensure high purity and batch-to-batch consistency, suitable for demanding research applications. Each batch undergoes rigorous analytical testing, including HPLC for purity and MS for identity confirmation. A comprehensive Certificate of Analysis (COA) detailing all test results 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 product is hygroscopic (moisture-sensitive); allow the sealed vial to equilibrate to room temperature before opening to minimize moisture uptake. For extended storage, consider desiccant in the storage environment.
