The CLB-IVC7 monoclonal antibody specifically binds to CD36 which is also known as Glycoprotein IIIb (GPIIIb, GP3B), Platelet glycoprotein IV (GPIV), Fatty acid translocase (FAT), Platelet collagen receptor (PASIV), Scavenger receptor class B member 3 (SCARB3) or Thrombospondin receptor. CD36 is a ~88 kDa transmembrane that belongs to the scavenger receptor superfamily. The CD36 antigen is expressed on platelets, megakaryocytes, monocytes, macrophages, dendritic cells, erythroid precursors, adipocytes, and some endothelial and epithelial cells. The CD36 antigen is the receptor for extracellular matrix proteins such as collagen and thrombospondin. The CD36 antigen can mediate the adhesion of erythrocytes infected with the human malaria parasite, Plasmodium falciparum. The CD36 antigen functions as a scavenger receptor in macrophages.
The antibody was conjugated to BD Horizon™ BUV563 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome of BD Horizon BUV395 which has an Ex Max of 348 nm and an acceptor dye. The tandem has an Em Max at 563 nm. BD Horizon BUV563 can be excited by the 355 nm ultraviolet laser. On instruments with a 561 nm Yellow-Green laser, the recommended bandpass filter is 585/15 nm with a 535 nm long pass to minimize laser light leakage. When BD Horizon BUV563 is used with an instrument that does not have a 561 nm laser, a 560/40 nm filter with a 535 nm long pass may be more optimal. Due to the excitation and emission characteristics of the acceptor dye, there may be spillover into the PE and PE-CF594 detectors. However, the spillover can be corrected through compensation as with any other dye combination.
