CD86 PE-Fire 640 (IT2.2, Mouse) - Reactivity: Cynomolgus macaque, Human, Rhesus macaque

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 PE-Fire 640
PE-Fire™ 640 from Biolegend is a red-emitting tandem fluorophore that combines pycoerythrin (PE) and Fire™ 640. The donor molecule, PE can be excited by the 488-nm blue, 532-nm green, or 561-nm yellow-green laser and and transfers energy to the acceptor molecule, Fire™ 640, which emitts light that can be captured with a 630/69 nm bandpass filter. PE-eF610 has an excitation peak at 565 nm and an emission peak at 639 nm. In spectral cytometry, this dye can be accurately unmixed from other dyes with highly overlapping spectral profiles, such as PE-Dazzle® 594 and PE-Cy5. PE-Fire™ 640 is recommended for labeling antigens that: (1) are expressed on a small subset (2) will be excluded from final analysis, and (3) require a bright signal but are not co-expressed with an antigen marked by a dye with overlapping spectra.
