Anti-XPD antibodies enable researchers to detect and measure the XPD antigen in biological samples. This target is a reported synonym of the ERCC2 gene, which encodes ERCC excision repair 2, TFIIH core complex helicase subunit. This protein is known to function in pathways of aging and the apoptotic pathway, among other biological roles. The human version of XPD has a canonical amino acid length of 760 residues and a protein mass of 86.9 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include COFS2, EM9, and TFIIH. Western Blot is the most common application for the XPD antibodies listed below. ELISA and Immunohistochemistry are also common applications.
