Anti-DUSP21 antibodies are used in the immunodetection of the protein dual specificity phosphatase 21. In humans, the canonical protein has a reported length of 190 amino acid residues and a mass of 21.5 kDa. Its subcellular localization is in the nucleus, mitochondria, and cytoplasm. It is notably expressed in the testis. It is a member of the Protein-tyrosine phosphatase protein family. Synonyms for this target antigen include BJ-HCC-26 tumor antigen, LMW-DSP21, low molecular weight dual specificity phosphatase 21, and dual specificity protein phosphatase 21. DUSP21 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. ELISA is the most common application for the Dusp21 antibodies listed below. Immunocytochemistry and Immunofluorescence are also common applications.
