The MJ7/18 monoclonal antibody specifically binds to mouse CD105 (also known as endoglin) which is a homodimer of 90-kDa subunits and is predominantly expressed on vascular endothelial cells. High levels of mouse endoglin mRNA have been reported to be detectable in the ovary, uterus, NCTC-2071 fibroblasts, and to a lesser extent, in heart, muscle and stromal cells in connective tissue of various organs. Endoglin has been reported to play an essential role in embryonic angiogenesis. Both mouse and human endoglin display strong amino-acid sequence homology to the transmembrane and cytoplasmic regions of the type III TGF-ß receptor.
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).
