AAT Bioquest's mFluor™ dyes are developed for flow cytometry-focused applications. These dyes have large Stokes Shifts, and can be well excited by the laser lines of flow cytometers (e.g., 405 nm, 488 nm and 633 nm). mFluor™ Violet 520 dyes have fluorescence excitation and emission maxima of ~405 nm and ~520 nm respectively. mFluor™ Violet 520 SE is reasonably stable and shows good reactivity and selectivity with protein amino groups. This kit has all the essential components to perform five separate labeling reactions and purifications. Each of the five vials of mFluor™ Violet 520 SE provided in the kit is optimized for labeling ~100 µg antibody. mFluor™ Violet 520 SE antibody labeling kit provides a convenient method to label small amounts of monoclonal, polyclonal antibodies or other proteins (>10 kDa) with the Violet Laser-excitable mFluor™ Violet 520 SE
