These APO3 ELISA kits are immunodetection tools for measuring the levels of APO3 in biological samples. APO3 is an alias of the human TNFRSF25 gene, which encodes the protein, TNF receptor superfamily member 25. Notably, APO3 is known to play a role in the apoptotic pathway and receptor-mediated signaling pathways, among other functions. The TNFRSF25 protein is 417 amino acid residues in length and 45.4 kilodaltons in mass. However, as many as 12 protein isoforms have been identified. In terms of tissue specificity, it is found to be highly expressed in thymocytes and lymphocytes. This protein is known to be glycosylated. Other names for this target antigen include DDR3.
