mFluor™ UVB 460 SE

mFluor™ UVB 460 SE is an amine-reactive dye optimally excited at 320 nm that provides a distinct blue emission channel for creating multiparameter flow cytometry panels with UV laser systems.

Extended UV-to-Blue Emission: Excitation at ~320 nm with emission at ~460 nm creates an exceptionally large Stokes shift for reduced spectral crosstalk in multicolor panels
Unique Spectral Niche: Fills a rare spectral window with minimal overlap with conventional fluorophores
High Extinction Coefficient: Strong absorption (166,181 cm⁻¹M⁻¹) ensures efficient excitation and bright signal generation with standard UV laser lines
Optimized for Abundant Markers: Small organic dye structure ideal for antibody conjugation, recommended for high-expression targets like CD4

Overview

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., 355 nm, 405 nm, 488 nm and 633 nm). mFluor™ UVB 460 dyes have fluorescence excitation and emission maxima of ~320 nm and ~460 nm respectively. These spectral characteristics make them a unique color for designing multicolor flow cytometry panels. mFluor™ UVB 460 dyes are well excited by UV laser of 320 nm with emission centered around 460 nm. It is particularly useful for spectral flow cytometry since there are very few existing fluorescent dyes that overlap with their spectra. They are small organic molecules that can be readily conjugated to antibodies. We recommend them to be used for brighter markers (such as CD4).
