Anti-CD140a antibodies are protein reagents that detect specific antigens. The CD140a antigen is another term for the human protein platelet derived growth factor receptor alpha, encoded by the PDGFRA gene. The protein is reported to be a tyrosine-protein kinase that acts as a cell-surface receptor for PDGFA, PDGFB and PDGFC and plays an essential role in the regulation of embryonic development, cell proliferation, survival and chemotaxis. Canonically, it has an amino acid length of 1089 residues and a mass of 122.7 kilodaltons. Its subcellular localization is in the Golgi and cell membrane and it is notably expressed in platelets. The CD140a protein is a member of the Tyr protein kinase protein family. Other alias names for CD140a include PDGFR-2. Some CD140a antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
