AQuora® 405-NHS Ester (QBD-12005LF)


AQuora® 405-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® 405-NHS Ester 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® 405-NHS Ester is a pyrene-based dye with photophysical properties comparable to Alexa Fluor 405® and DyLight® 405. (Alex Fluor® and DyLight® are trademarks of Thermo Fisher Scientific.) This AQuora® 405-NHS Ester 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.
