The 3D6 monoclonal antibody specifically binds to c-Met (MET), which is also known as Hepatocyte growth factor receptor (HGFR) or Scatter factor receptor (SF receptor). c-Met is a 190 kDa single-pass type I transmembrane glycoprotein that is posttranslationally cleaved into a disulfide-linked extracellular α-chain and a transmembrane β-chain. c-Met functions as a receptor tyrosine kinase (RTK) that is normally involved in the development, regeneration, and survival of cells and tissues. c-Met is expressed on a variety of cell types including stem cells and progenitor cells, hepatocytes, keratinocytes, epithelial cells, endothelial cells, and neurons. c-Met is autophosphorylated when bound by its ligand, Hepatocyte Growth Factor (HGF). This leads to further activation of downstream signaling pathways that induce multiple responses including cellular migration, proliferation, survival, and angiogenesis. Abnormal c-Met expression or activity has been associated with tumorigenesis. The 3D6 antibody can reportedly function as an agonist by binding to and activating human but not mouse c-Met.
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.
