CD42d Mouse Anti-Rat, Brilliant Violet 711, Clone: RPM.4, BD Optibuild™

Description

The RPM.4 monoclonal antibody specifically recognizes CD42d (Platelet glycoprotein V, GPV). CD42d is a 88-kDa type I transmembrane glycoprotein which noncovalently associates with GPIb and GPIX to form a receptor for von Willebrand factor on megakaryocytes and resting platelets. The binding sites for von Willebrand factor and thrombin have been localized to the GPIb chain of the GPI-b-V-IX complex. GPV is cleaved by thrombin to release a 70 kDa soluble fragment, which contains the epitope recognized by mAb RPM.4. Although the rat CD42d protein's structure is similar to that of human CD42d, the RPM.4 antibody does not cross-react with human platelets.

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 405nm and an acceptor dye with an Em Max at 711nm. 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, 712/20nm 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. BV711 is a tandem fluorochrome of BD Horizon BV421 and an acceptor dye with an emission maximum at 711 nm. This dye offers a very bright choice for the violet laser. 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. BV711 will also have moderate spillover into the BD Horizon Brilliant™ Violet 786 detector.
