mFluor™ Violet 450 Azide

AAT Bioquest's mFluor™ dyes are developed for multicolor 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 450 dyes have fluorescence excitation and emission maxima of ~405 nm and ~450 nm respectively. These spectral characteristics make them an excellent replacement for Pacific Blue™ labeling dye. mFluor™ Violet 450 azide is quite stable and shows good reactivity and selectivity with an alkyne group. mFluor™ Violet 450 azide provides a convenient tool to label an alkyne-modified biomolecule.
