About CX3CR1
Fractalkine is a transmembrane protein and chemokine involved in the adhesion and migration of leukocytes. The protein encoded by this gene is a receptor for fractalkine. The encoded protein also is a coreceptor for HIV-1, and some variations in this gene lead to increased susceptibility to HIV-1 infection and rapid progression to AIDS. Four transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jan 2010]

About Brilliant Violet 785
Brilliant™ Violet 785 (BV785) is a far-red-emitting tandem fluorophore that can be excited by the 405 nm Violet laser and collected using a 780/60 bandpass filter. BV785 has an excitation peak at 405 nm and an emission peak at 785 nm. BV785 exhibits a medium level of brightness and is most often used in flow cytometry. Older instruments may not be set up for a dye with such a large Stokes shift, however BV785 is especially well suited for spectral cytometers or sorters. This dye is part of the Brilliant™ Violet dye line of fluorescent polymers. Brilliant™ Violet 421 polymer is employed as the donor molecule in a series of tandem dyes with acceptor molecules emitting at various points across the visible light spectrum. The Brilliant™ Violet dyes are a superior alternative to QDot nanocrystals and similar to SuperNova dye from Beckman Coulter and StarBright dyes from Bio-Rad.
