Quality Control

Our 80K Protein is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing specifications such as purity (by HPLC), molecular weight confirmation, endotoxin levels, and bioburden is provided to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C for long-term stability. This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent moisture absorption. For extended storage, consider aliquoting and freezing at -20°C or below.
