Anti-Top3 antibodies enable researchers to detect and measure the Top3 antigen in biological samples. This target is a reported synonym of the TOP3A gene, which encodes DNA topoisomerase III alpha. This protein is known to function in DNA repair, among other biological roles. The human version of Top3 has a canonical amino acid length of 1001 residues and a protein mass of 112.4 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. Other names for this target antigen include MGRISCE2 and PEOB5. Western Blot is a widely used application for the Top3 antibodies listed below. In addition, ELISA is also a common application.
