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 605
Brilliant™ Violet 605 (BV605) is an orange/red-emitting tandem fluorophore that can be excited by the 405 nm Violet laser and collected using a 610/20 bandpass filter. BV605 has an excitation peak at 405 nm and an and emission peak at 603 nm. BV605 is most commonly used in flow cytometry and is spectrally similar to SuperBright 600 (Thermo Fisher), SuperNova v605 (Beckman Coulter) and StarBright Violet 610 (Bio-Rad). BV605 is considered to be relatively bright and should be used on antigens of moderate to low abudance. 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.
