mFluor™ Blue 660 SE
mFluor™ Blue 660 dye can be well excited with blue laser at 488 nm. It has a huge Stokes shift with emission ~660 nm. mFluor™ Blue 660 dyes are water-soluble, and the protein conjugates prepared with mFluor™ Blue 660 dyes are well excited at 488 nm to give red fluorescence. mFluor™ Blue 660 dye and conjugates are excellent blue laser reagents for flow cytometry detections. Compared to RPE, mFluor™ Blue 660 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 special spectral profile.
Flow cytometry analysis of whole blood stained with mFluor™ Blue 660 anti-human CD4 *SK3* conjugate. The fluorescence signal was monitored using an Aurora spectral flow cytometer in the mFluor™ Blue 660 specific B9-A channel.
