The CRF D-2712 monoclonal antibody specifically binds to mouse and rat CD36, an 88-kDa glycoprotein member of the class B scavenger receptor family. CD36 is a multifunctional receptor that has a variety of ligands and is expressed on many cell types. Consequently, it is known by several names, including macrophage scavenger receptor, platelet glycoprotein IV, and fatty acid translocase. Cells that express CD36 include platelets, megakaryocytes, monocytes/macrophages, dendritic cells, erythroid precursors, microvascular endothelia, skeletal, cardiac, and smooth muscle cells, adipocytes, and epithelia of retina, breast, and intestine. This multi-ligand receptor functions in the clearance of apoptotic cells and abnormal erythrocytes (in malaria and sickle-cell anemia), the transport of long-chain fatty acids and oxidized low-density lipoproteins, the regulation of angiogenesis by mediating the effects of thrombospondin-1, and the mediation of coronary vasoconstriction. Crosslinking of cell-surface CD36 with plate-bound CRF D-2712 antibody promotes internalization of photoreceptor outer segment fragments by cultured retinal pigment epithelium.
The antibody was conjugated to BD Horizon BB515 which is part of the BD Horizon Brilliant™ Blue family of dyes. With an Ex Max near 490 nm and an Em Max near 515 nm, BD Horizon BB515 can be excited by the blue laser (488 nm) laser and detected with a 530/30 nm filter. This dye has been exclusively developed by BD Biosciences and is up to seven times brighter than FITC with less spillover into the PE channel. Due to similar excitation and emission properties, BB515, FITC, and Alexa Fluor® 488 cannot be used simultaneously. It is not recommended to use BB515 in cocktails that include Streptavidin conjugates as it may cause high background.
