About CD86
This gene encodes a type I membrane protein that is a member of the immunoglobulin superfamily. This protein is expressed by antigen-presenting cells, and it is the ligand for two proteins at the cell surface of T cells, CD28 antigen and cytotoxic T-lymphocyte-associated protein 4. Binding of this protein with CD28 antigen is a costimulatory signal for activation of the T-cell. Binding of this protein with cytotoxic T-lymphocyte-associated protein 4 negatively regulates T-cell activation and diminishes the immune response. Alternative splicing results in several transcript variants encoding different isoforms.[provided by RefSeq, May 2011]

About Brilliant Violet 786
Brilliant™ Violet 786 (BV786) 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. BV750 has an excitation peak at 405 nm and an emission peak at 786 nm. Due to its unique Stokes shift, few dyes have identical or near identical excitation and emission spectrums, but the nearest alternatives are Qdot® 800 and SuperBright 780 (ThermoFisher), and Brilliant™ Violet 785 (BioLegend). What's the difference between BV785 and BV786? BV785 is a BioLegend color, while BV786 is a BD Biosciences color, but they exhibit the same spectral properties. This dye 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 BV786 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.
