Anti-DUSP19 antibodies are used in the immunodetection of the protein dual specificity phosphatase 19. In humans, the canonical protein has a reported length of 217 amino acid residues and a mass of 24.2 kDa. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in the heart, lung, liver, and pancreas. A member of the Protein-tyrosine phosphatase protein family, DUSP19 is known to have a dual specificity toward Ser/Thr and Tyr-containing proteins. Synonyms for this target antigen include SAPK pathway-regulating phosphatase 1, dual specificity phosphatase TS-DSP1, low molecular weight dual specificity phosphatase 3, protein phosphatase SKRP1, and dual specificity protein phosphatase 19. DUSP19 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some DUSP19 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
