Quality Control

Every batch of Fluorescence Red 610 Reactive* is manufactured under strict quality management systems. Our products undergo rigorous quality testing, including HPLC for purity and spectral analysis for performance verification, to ensure consistency and compliance with research-grade standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, absorbance, and fluorescence properties is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store desiccated at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and hydrolysis of the reactive group.
