Fluidiphore Rapid Amine 503


Fluidiphore rapid amine 503

Labeling made easy—labeling made rapid


Quick and easy to use protein labeling kit.

The fluidiphore rapid protein labeling kit is an easy to use protein labeling kit that only needs 30 minutes incubation time and zero purification. The background effects from unbound dye are eliminated due to the absorbance wavelength shifting and an increase in quantum yield once the dye is conjugated to its binding partner, meaning no purification is required. Additionally unreacted dye is hydrolyzed during the labeling procedure.

The fluidiphore rapid amine 503 is an amine-reactive fluorescent label that once conjugated to its binding partner absorbs at 503 nm making it compatible with Fluidic Analytics’ fluidity One-W instrument.
