The RL73 monoclonal antibody specifically binds to mouse CD147. CD147 is type I membrane glycoprotein and member of the Ig superfamily. CD147 is also known as extracellular matrix metalloproteinase inducer (EMMPRIN) and gp42/basigin (BSG). The CD147 molecule is widely expressed on a variety of hemopoietic and non-hemopoietic cell types including thymocytes, lymphocytes, monocytes, granulocytes, erythroblasts and erythrocytes, endothelial cells and neoplasms. CD147 reportedly plays significant roles in the reproductive, nervous and immune systems and in tumor progression. In the immune system, CD147 can function as an adhesion molecule and signaling receptor that regulates leukocyte trafficking and immune and inflammatory responses.
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.
