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™ BUV805 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome of BD Horizon BUV395 with an Ex Max of 348 nm and an acceptor dye with an Em Max at 805 nm. BD Horizon Brilliant BUV805 can be excited by the ultraviolet laser (355 nm) and detected with a 820/60 filter and a 770LP.
