Anti-XPB antibodies enable researchers to detect and measure the XPB antigen in biological samples. This target is a reported synonym of the ERCC3 gene, which encodes ERCC excision repair 3, TFIIH core complex helicase subunit. This protein is known to function in the apoptotic pathway and DNA repair, among other biological roles. The human version of XPB has a canonical amino acid length of 782 residues and a protein mass of 89.3 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Other names for this target antigen include BTF2, GTF2H, and RAD25. Indicated applications for XPB antibodies listed below include ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry.
