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 BUV615 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome with an Ex Max near 350 nm and an Em Max near 615 nm. BD Horizon Brilliant BUV615 can be excited by the ultraviolet laser (355 nm) and detected with a 610/20 filter and a 595 nm LP. Due to the excitation of the acceptor dye by the blue/yellow-green laser line, there may be significant spillover into channels detecting PE-CF594 like emissions (eg, 610/20-nm filter).
