Anti-PLAC1 antibodies are used in the immunodetection of the protein placenta enriched 1. In humans, the canonical protein has a reported length of 212 amino acid residues and a mass of 23.6 kDa. It has been described to be a secreted protein. It is notably expressed in the placenta. A member of the PLAC1 protein family, PLAC1 is believed to play a role in placental development. Synonyms for this target antigen include OOSP2B, OOSP2L, placenta-specific protein 1, cancer/testis antigen 92, placenta specific 1, and CT92. PLAC1 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. A number of PLAC1 antibodies have been mentioned in research publications and have associated citations. ELISA is a widely used application for these antibodies. Western Blot, Immunocytochemistry, and Immunofluorescence are also common applications.
