A number of ELISA Kits are available that target TNFa, an alias of the protein, tumor necrosis factor. The human protein, encoded by the gene TNF, is a member of the Tumor necrosis factor family. The protein's cellular localization is indicated to be membrane-associated and secreted. Additional synonyms or past names for this protein may include: DIF, TNF-alpha, TNFA, TNFSF2, TNLG1F. Homology is conserved in other species, such as Mouse, Rat, Zebrafish, Frog.
