The FA6-152 monoclonal antibody specifically binds to CD36, an ~88 kDa transmembrane glycoprotein which belongs to the class B scavenger receptor family. This scavenger receptor contains a heavily glycosylated extracellular domain followed by two transmembrane segments and N- and C-terminal cytoplasmic tails. CD36 is expressed on platelets, megakaryocytes, monocytes/macrophages, dendritic cells (DCs), erythroid precursors, microvascular endothelia, skeletal, cardiac, and smooth muscle cells, adipocytes, and epithelia of retina, breast, and intestine. This multifunctional receptor plays essential roles in lipid homeostasis, angiogenesis, immune response, adhesion, and cancer progression. CD36 is also a very early marker of erythroid differentiation. In platelets, CD36 promotes activation, aggregation and secretion. Among blood cells, the FA6-152 antibody binds to both adult and fetal monocytes, platelets, and reticulocytes, but does not react with lymphocytes and granulocytes. This antibody reportedly blocks CD36 interactions with thrombospondin, collagen, apoptotic cells, and modified LDL and induces agglutination of fetal but not adult erythrocytes.
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application. For optimal and reproducible results, BD Horizon Brilliant™ Stain Buffer should be used anytime BD Horizon Brilliant™ dyes are used in a multicolor flow cytometry panel. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant Stain Buffer is used in in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant Stain Buffer for the same length of time as the corresponding multicolor panel. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385). For optimal results, it is recommended to perform two washes after staining with antibodies. Cells may be prepared, stained with antibodies and washed twice with wash buffer per established protocols for immunofluorescent staining prior to acquisition on a flow cytometer. Performing fewer than the recommended wash steps may lead to increased spread of the negative population.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions that minimize unconjugated dye and antibody.
