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 an oligonucleotide that contains an antibody clone-specific barcode (ABC) flanked by a poly-A tail on the 3' end and a PCR handle (PCR primer binding site) on the 5' end. The ABC for this antibody was designed to be used with other BD AbSeq oligonucleotides conjugated to other antibodies. All AbSeq ABC sequences were selected in silico to be unique from human and mouse genomes, have low predicted secondary structure, and have high Hamming distance within the BD AbSeq portfolio, to allow for sequencing error correction and unique mapping. The poly-A tail of the oligonucleotide allows the ABC to be captured by the BD Rhapsody™ system. The 5' PCR handle allows for efficient sequencing library generation for Illumina sequencing platforms.
NOTE: The BD Rhapsody Single-Cell Analysis System must be used with the BD Rhapsody Express Instrument.
