Anti-CTDSPL2 antibodies are used in the immunodetection of the protein CTD small phosphatase like 2. In humans, the canonical protein has a reported length of 466 amino acid residues and a mass of 53 kDa. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the CTDSPL2 protein family, CTDSPL2 is a suspected phosphatase. Synonyms for this target antigen include HSPC129, SCP4, CTD small phosphatase-like protein 2, CTD (carboxy-terminal domain, RNA polymerase II, polypeptide A) small phosphatase like 2, CTDSP-like 2, and HSPC058. CTDSPL2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of CTDSPL2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
