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 650
Brilliant™ Violet 650 (BV650) is a red-emitting tandem fluorophore that can be excited by the 405 nm Violet laser and collected using a 660/20 bandpass filter. BV650 has an excitation peak at 405 nm and an emission peak at 645 nm. Due to its unique Stokes shift, not many dyes have identical excitation and emission spectrums, but the nearest alternatives include SuperBright 645, Qdot® 655 and eFluor™ 650NC (ThermoFisher). BV650 exhibits a medium level of brightness and is most often used in flow cytometry, specifically, it is an alternative to nanocrystals used for intracellular flow. 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.
