The VIM5 monoclonal antibody specifically recognizes CD87. CD87 is also known as the urokinase plasminogen activator receptor (uPA-R). CD87 is a 50-65 kDa single chain glycosylphosphatidylinositol (GPI)-linked glycoprotein. uPA-R was clustered as CD87 in the Fifth Human Leukocyte Differentiation Antigens Workshop. It is expressed on neutrophils, monocytes, macrophages, dendritic cells, endothelial cells, activated T cells, fibroblasts, and smooth muscle. CD87 plays a role in cell-associated fibrinolytic activity and tissue invasion. This antibody may be useful in the study of myeloid cell differentiation.
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.
