AQuora® Fluorescein-Maleimide (QBD-11590LF)



AQuora® Fluorescein-Maleimide is a thiol-reactive fluorophore engineered with SuperHydrophilic™ technology designed to improve solubility during labeling and of the dye-labeled conjugate. As a result, the dye-labeled conjugates made with AQuora® Fluorescein-Maleimide yield enhanced signal and signal-to-noise ratios in fluorescence-based applications, including fluorescent western blotting, fluorescence-based microscopy, flow cytometry, and cell-based assays. AQuora® Fluorescein-Maleimide is a xanthene-based dye with photophysical properties comparable to FITC and Carboxyfluorescein.

This AQuora® Fluorescein-Maleimide dye is activated with a maleimide (MAL) group, which reacts with a thiol to form a thioether bond.
