Anti-STPG3 antibodies are used in the immunodetection of the protein sperm-tail PG-rich repeat containing 3. In humans, the canonical protein has a reported length of 386 amino acid residues and a mass of 42.5 kDa. Up to 4 different isoforms have been reported for this protein. Synonyms for this target antigen include protein STPG3 and sperm-tail PG-rich repeat-containing protein 3. STPG3 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Western Blot is the most common application for the STPG3 antibodies listed below. Immunocytochemistry and Immunofluorescence are also common applications.
