Anti-PLAC9 antibodies are used in the immunodetection of the protein placenta associated 9. In humans, the canonical protein has a reported length of 97 amino acid residues and a mass of 10.3 kDa. It has been described to be a secreted protein. It is a member of the PLAC9 protein family. Synonyms for this target antigen include placenta-specific protein 9 and placenta specific 9. PLAC9 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some PLAC9 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
