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 Ultraviolet 805
Brilliant™ UltraViolet 805 (BUV805) is a infrared-emitting tandem fluorophore that combines BD Horizon® BUV395 and an acceptor dye. It can be excited by the 355 nm ultraViolet laser and collected using a 820/60 bandpass filter. BUV805 has an excitation peak at 498 nm and an emission peak at 797 nm BUV805 has a low relative brightness, and is most commonly used for multicolor flow cytometry. This dye is part of the Brilliant™ UltraViolet dye family, developed and sold by BD Biosciences. This family of dyes uses BUV396 as the donor so that all dyes in the family can be excited by the 355 nm ultraViolet laser. Depending on the acceptor, the dyes in this family have different relative brightness ratings.
