The Fn14 ELISA kits listed below are analytical tools for measuring concentrations of Fn14 in various samples. Fn14 is an alternative name for the human TNFRSF12A gene, which encodes the protein, TNF receptor superfamily member 12A. It has been mentioned that Fn14 plays a role in angiogenesis and the apoptotic pathway, among other functions. Structurally, the TNFRSF12A protein is 129 amino acid residues in length and 13.9 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the membrane of the cell. In terms of tissue specificity, it is reported to be highly expressed in heart, placenta and kidney. Other names for this target antigen include CD266 and CD266. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
