Quality Control

Our Gb1-Cyanine 3 is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and performance for sensitive research and diagnostic applications. Certificates of Analysis (COA) detailing purity, absorbance/fluorescence profiles, and other critical parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as indicated on the label. This product is hygroscopic (moisture-sensitive) and light-sensitive; desiccants are recommended for long-term storage. Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture uptake.
