AQuora® PB-Maleimide (QBD-12019LF)



AQuora® PB-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® PB-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® PB-Maleimide is a coumarin-based dye with photophysical properties comparable to Pacific Blue. It is activated with a maleimide (MAL) group, which reacts with a thiol to form a thioether bond. (Pacific Blue® is a registered trademark of Thermo Fisher Scientific.)
