Anti-TNFRSF18 antibodies are useful in the immunodetection of TNFRSF18. This target gene encodes the protein 'TNF receptor superfamily member 18' in humans and may also be known as CD357, GITR, tumor necrosis factor receptor superfamily member 18, AITR, ENERGEN, and TNF receptor superfamily activation-inducible protein. Structurally, the protein is reported to be 26 kilodaltons in mass. Based on gene name, canine, porcine, monkey, mouse, and rat orthologs may also be found.
