CD4 Rat anti-Mouse, Brilliant Violet 650, Clone: RM4-4, BD Optibuild
Rat Monoclonal Antibody
Manufacturer: BD Biosciences 740446
The RM4-4 monoclonal antibody specifically binds to CD4 (L3T4) differentiation antigen expressed on most thymocytes, a subpopulation of mature T lymphocytes (ie, MHC class II-restricted T cells, including most T helper cells), and a subset of NK-T cells of all mouse strains tested. CD4 has also been detected at low density on pluripotent hematopoietic stem cells, bone marrow myeloid and B-lymphocyte precursors, intrathymic lymphoid precursors, and a subset of splenic dendritic cells. CD4 is expressed on the plasma membrane of mouse egg cells and is involved in adhesion of the egg to MHC class II-bearing sperm. CD4 is an antigen coreceptor on the T-cell surface which interacts with MHC class II molecules on antigen-presenting cells. It participates in T-cell activation through its association with the T-cell receptor complex and protein tyrosine kinase lck. Purified RM4-4 mAb does not block binding of the CD4-specific monoclonal antibodies, GK1.5, H129.19, or RM4-5, to T cells.
The antibody was conjugated to BD Horizon BV650 which is part of the BD Horizon Brilliant Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 650-nm. BD Horizon BV650 can be excited by the violet laser and detected in a filter used to detect APC-like dyes (eg, 660/20-nm filter). Due to the excitation and emission characteristics of the acceptor dye, there will be spillover into the APC and Alexa Fluor 700 detectors. However, the spillover can be corrected through compensation as with any other dye combination.
