These XPB ELISA kits are immunodetection tools for measuring the levels of XPB in biological samples. XPB is an alias of the human ERCC3 gene, which encodes the protein, ERCC excision repair 3, TFIIH core complex helicase subunit. Notably, XPB is known to play a role in the apoptotic pathway and DNA repair, among other functions. The ERCC3 protein is described to be 782 amino acid residues in length and 89.3 kilodaltons in mass. It is localized to the nucleus of the cell. Other names for this target antigen include BTF2, GTF2H, and RAD25. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
