Anti-TNFalpha antibodies are protein reagents that detect specific antigens. The TNFalpha antigen is another term for the human protein tumor necrosis factor, encoded by the TNF gene. The protein is a reported to be a cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. Canonically, it has an amino acid length of 233 residues and a mass of 25.6 kilodaltons. Its subcellular localization is in the cell membrane and is secreted. It is expressed in the tonsil. The TNFalpha protein is a member of the Tumor necrosis factor protein family. Other alias names for TNFalpha include DIF and TNFA. Over 4900 citations in the literature describe the use of TNFalpha antibodies in research. Western Blot is a widely used application for these antibodies. ELISA and Flow Cytometry are also common applications.
