About
mFluor™ UV375 SE
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™ UV375 (MFUV375) dyes have fluorescence excitation and emission maxima of ~355 nm and ~375 nm respectively. These spectral characteristics make them an excellent alternative to BD Biosciences' BUV395. mFluor™ UV375 dyes are well excited by UV laser of 355 nm with emission centered around 375 nm, which perfectly matches the filter set of 379/28 nm used for BUV 395. In contrast to polymer-based BUV 395 dye, MFUV375 is a small organic molecule that can be readily conjugated to antibodies. It is significantly dimmer than BUV395, might be used for brighter markers (such as CD4).
(Top) Spectral emission profiles generated using four spatially offset lasers (355 nm, 405 nm, 488 nm, and 640 nm). Each laser produced a distinct emission pattern, and their combination yielded the composite spectral signature. (Bottom) Flow cytometry analysis of whole blood stained with mFluor™ UV375 Anti-human CD4 conjugate. The fluorescence signal was monitored using an Aurora spectral flow cytometer in the specific UV1-A channel.
