The C34-3448 monoclonal antibody specifically binds to CD195 which is also known as, C-C chemokine receptor type 5 (CCR5). CD195 is a seven transmembrane-spanning G-protein-coupled receptor that belongs to the β-chemokine receptor family. CD195 regulates lymphocyte chemotaxis activation and transendothelial migration during inflammation. It signals in response to at least three chemokines: CCL3/MIP-1α, CCL4/MIP-1β, and CCL5/RANTES. CD195 is expressed on macrophages and some T-lymphocytes.
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).
