The M-T701 monoclonal antibody specifically binds to CD7. CD7 is a 40 kDa type I transmembrane glycoprotein that belongs to the immunoglobulin superfamily. The CD7 antigen is also known as Leu-9, TP41, Tp40, GP40, and T-cell leukemia antigen. It is expressed on thymocytes, T cells, pre-B cells, and NK cells. CD7 is present in reduced density on monocytic cells and cell lines. Functional studies demonstrate that crosslinking of the CD7 can induce transmembrane calcium flux in T cells.
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).
