Anti-CTDSP2 antibodies are used in the immunodetection of the protein CTD small phosphatase 2. In humans, the canonical protein has a reported length of 271 amino acid residues and a mass of 30.7 kDa. Its subcellular localization is in the nucleus. CTDSP2 is known to be involved with protein dephosphorylation. Synonyms for this target antigen include PSR2, SCP2, carboxy-terminal domain RNA polymerase II polypeptide A small phosphatase 2, CTD (carboxy-terminal domain, RNA polymerase II, polypeptide A) small phosphatase 2, and OS4. CTDSP2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Western Blot is a widely used application for the CTDSP2 antibodies listed below. In addition, Immunohistochemistry is also a common application.
