AQuora® PB-NHS Ester (QBD-12018LF)



AQuora® PB NHS Ester is an amine-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 NHS Ester (Pacific Blue) 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 NHS Ester is a coumarin-based dye with photophysical properties comparable to Pacific Blue.

This AQuora® PB NHS Ester (Pacific Blue) dye is activated with an N-hydroxysuccinimide (NHS) ester group, which reacts with free primary amines, such as the amines on the side chain of lysines, forming a stable amide bond.

Pacific Blue is a trademark of Thermo Fisher Scientific.
