The LpMab-17 monoclonal antibody specifically recognizes human podoplanin which is encoded by PDPN. Podoplanin is a 38-44 kDa type I transmembrane glycoprotein. This heavily glycosylated mucin type protein is named for its expression on kidney glomerular epithelial cells known as podocytes. It is also expressed on a wide variety of cell types, including intestinal and thymic epithelial cells, alveolar type I cells, fibroblastic reticular cells, lymphatic endothelial cells, osteoblasts, and Th17 cells. Its expression is upregulated in some tumors. Podoplanin induces platelet aggregation via its three platelet aggregation-stimulating (PLAG) domains; it binds C-type lectin domain family 1 member B (Clec1B, also known as CLEC2); and it is involved in actin cytoskeleton organization and in cellular adhesion and migration. It also plays roles in organogenesis, vascular development, inflammatory diseases, tumorigenesis, and cancer cell motility and metastasis.
The antibody was conjugated to BD Horizon Red 718, which has been developed exclusively for BD Biosciences as a better alternative to Alexa Fluor® 700. BD Horizon Red 718 can be excited by the red laser (628 – 640 nm) and, with an Em Max around 718 nm, it can be detected using a 730/45 nm filter. Due to similar excitation and emission properties, we do not recommend using R718 in combination with APC-R700 or Alexa Fluor® 700.
