The 235614 monoclonal antibody specifically binds to CRACC (CD2-like receptor activating cytotoxic cells) which is also known as CD319, CS1 (CD2 subset 1), SLAMF7, 19A, and 19A24. CRACC is a type I transmembrane glycoprotein that belongs to the CD2 family of receptors within the Ig superfamily. CRACC is expressed on most NK cells and subsets of CD8+ T cells, CD4+ T cells, B cells, macrophages, and dendritic cells. CRACC reportedly plays roles in the activation, proliferation and effector functions of T cells, NK cells, and other leucocytes.
The antibody was conjugated to BD Horizon™ BV711 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 711-nm. BD Horizon BV711 can be excited by the violet laser and detected in a filter used to detect Cy™5.5 / Alexa Fluor® 700-like dyes (eg, 712/20-nm filter). Due to the excitation and emission characteristics of the acceptor dye, there may be moderate spillover into the Alexa Fluor® 700 and PerCP-Cy5.5 detectors. However, the spillover can be corrected through compensation as with any other dye combination.
