Anti-TRAILR1 antibodies are protein reagents that detect specific antigens. The TRAILR1 antigen is another term for the human protein TNF receptor superfamily member 10a, encoded by the TNFRSF10A gene. The protein is a known receptor for the cytotoxic ligand TNFSF10/TRAIL. Canonically, it has an amino acid length of 468 residues and a mass of 50.1 kilodaltons. Its subcellular localization is in the cell membrane and cytoplasm and it is widely expressed across many tissue types. Other alias names for TRAILR1 include APO2, CD261, and DR4. Some TRAILR1 antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
