Anti-XPF antibodies enable researchers to detect and measure the XPF antigen in biological samples. This target is a reported synonym of the ERCC4 gene, which encodes ERCC excision repair 4, endonuclease catalytic subunit. This protein is known to function in DNA repair and autophagy pathways, among other biological roles. The human version of XPF has a canonical amino acid length of 916 residues and a protein mass of 104.5 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus and chromosomes of cells and widely expressed in many tissue types. Other names for this target antigen include ERCC11, FANCQ, and RAD1. These XPF antibodies are widely used in Western Blot experiments, among other applications.
