Advances in spectral flow cytometers have expanded applications and capabilities beyond conventional flow cytometry. Now with spectral flow cytometry analysis, researchers and scientists can investigate an increasing number of molecules of interest. However, the potential of spectral flow cytometry is severely limited by the availability of fluorescent labels and readouts. AAT Bioquest's mFluor™ dyes are developed for multicolor flow cytometry-focused applications, in particular, for spectral fluorescence flow cytometry. mFluor™ Green 630 dye can be well excited with green laser at 532 nm. It has a huge Stokes shift with emission ~630 nm. mFluor™ Green 630 dyes are water-soluble, and the protein conjugates prepared with mFluor™ Green 630 dyes are well excited at 532 nm to give red fluorescence. mFluor™ Green 630 dye and conjugates are excellent green laser reagents for flow cytometry detections. Compared to RPE, mFluor™ Green 630 dyes are much more photostable, making them readily available for fluorescence imaging applications while it is very difficult to use RPE conjugates for fluorescence imaging applications due to the rapid photobleaching of RPE conjugates. It is also a unique fluorochrome for spectral flow cytometry since there are very few existing dyes that have this spectral profile.
