The RCR-252 monoclonal antibody specifically binds to the endothelial cell protein C receptor (EPCR), which is also known as CD201. CD201 is a 25 kDa, type I transmembrane glycoprotein, expressed on endothelial cells in arteries, veins and capillaries. CD201 binds activated protein C, a serine protease that is involved in regulating blood coagulation. EPCR is reportedly expressed on several malignant cell lines. Malignant cell lines that express EPCR can show significant levels of protein C activation and this activation can be inhibited by anti-EPCR antibody
The antibody was conjugated to BD Horizon™ BV510 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 405-nm and Em Max at 510-nm, BD Horizon BV510 can be excited by the violet laser and detected in the BD Horizon V500 (525/50-nm) filter set. BD Horizon BV510 conjugates are useful for the detection of dim markers off the violet laser.
