Anti-TNFRI antibodies are protein reagents that detect specific antigens. The TNFRI antigen is another term for the human protein TNF receptor superfamily member 1A, encoded by the TNFRSF1A gene. The protein is a known receptor for TNFSF2/TNF-alpha and homotrimeric TNFSF1/lymphotoxin-alpha. Canonically, it has an amino acid length of 455 residues and a mass of 50.5 kilodaltons. Its subcellular localization is in the Golgi, cell membrane, and is secreted. It is widely expressed in many tissue types. Other alias names for TNFRI include CD120a, CD120a, and FPF. Some TNFRI antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
