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 Red 718, which has been developed exclusively for BD Biosciences as a better alternative to Alexa Fluor® 700. BD Horizon Red 718 can be excited by the red laser (628 – 640 nm) and, with an Em Max around 718 nm, it can be detected using a 730/45 nm filter. Due to similar excitation and emission properties, we do not recommend using R718 in combination with APC-R700 or Alexa Fluor® 700.
