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 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).
