Anti-SPACA7 antibodies are used in the immunodetection of the protein sperm acrosome associated 7. In humans, the canonical protein has a reported length of 195 amino acid residues and a mass of 21.5 kDa. Its subcellular localization is in the cytoplasmic vesicles and is secreted. It is reported to be expressed in spermatozoa. SPACA7 is known to be involved in fertilization. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include sperm acrosome-associated protein 7 and protein SPACA7. SPACA7 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Immunofluorescence is the most common application for the SPACA7 antibodies listed below. Western Blot, Immunocytochemistry, and Immunohistochemistry are also common applications.
