Anti-DUX3 antibodies are used in the immunodetection of the protein double homeobox 3. In humans, the canonical protein has a reported length of 197 amino acid residues and a mass of 22.1 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in hepatoma Hep3B cells. A member of the Paired homeobox protein family, DUX3 is known to be involved with the regulation of transcription. Synonyms for this target antigen include putative double homeobox protein 3. Western Blot is a widely used application for the DUX3 antibodies listed below. In addition, ELISA is also a common application.
