The CBR-IC2/2 monoclonal antibody specifically binds to CD102 which is also known as, intercellular adhesion molecule-2 (ICAM-2/ICAM2). CD102 is a type I transmembrane glycoprotein, member of the immunoglobulin supergene family, with an approximate molecular weight of 55-65 kDa. Its extracellular domain consists of two C2-type immunoglobulin-like subunits. The transmembrane region is 26 residues in size and the intracellular region also has 26 residues. CD102 is expressed on vascular endothelial cells, lymphocytes, monocytes, eosinophils, and platelets, but not on resting neutrophils. It is a ligand for the leukocyte integrin CD11a/CD18, or leukocyte function-associated antigen-1 (LFA-1), and there are reports of CD102 binding to leukocyte integrin CD11b/CD18 (Mac-1). Antibody CBR-IC2/2 blocks the binding of CD102 to leukocyte integrin CD11a/CD18. CD102 plays an important role in lymphocyte recirculation and in providing costimulatory signals in the immune response.
The antibody was conjugated to BD Horizon BUV615 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome with an Ex Max near 350 nm and an Em Max near 615 nm. BD Horizon Brilliant BUV615 can be excited by the ultraviolet laser (355 nm) and detected with a 610/20 filter and a 595 nm LP. Due to the excitation of the acceptor dye by the blue/yellow-green laser line, there may be significant spillover into channels detecting PE-CF594 like emissions (eg, 610/20-nm filter).
