The CW10 monoclonal antibody specifically binds to HVEM (Herpes virus entry mediator). HVEM is also known as CD270, Tumor necrosis factor receptor-like 2 (TR2), or LIGHT Receptor (LIGHT-R). CD270 is a type I transmembrane protein and member of the TNF Receptor superfamily. It is encoded by TNFRSF14 (tumor necrosis factor receptor superfamily member 14). CD270 is expressed on T cells, B cells, NK cells, monocytes, granulocytes, and some dendritic cells. CD270 binds to Lymphotoxin α (LTa3/TNFβ), CD258/LIGHT, CD272/BTLA, and glycoprotein D of Herpes simplex viruses HSV-1 and HSV-2. CD270-LIGHT interactions can reportedly transduce costimulatory signals for T cells whereas CD270-BTLA interactions can deliver inhibitory signals to T cells.
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.
