Anti-SCGB2A1 antibodies are used in the immunodetection of the protein secretoglobin family 2A member 1. In humans, the canonical protein has a reported length of 95 amino acid residues and a mass of 10.9 kDa. It has been described to be a secreted protein. It is reported to be expressed in thymus, trachea, kidney, steroid responsive tissues (prostate, testis, uterus, breast and ovary) and salivary gland. A member of the Secretoglobin protein family, SCGB2A1 is believed to bind androgens and other steroids, may also bind estramustine, a chemotherapeutic agent used for prostate cancer. Synonyms for this target antigen include LPNC, MGB2, UGB3, mammaglobin-B, lacryglobin, lipophilin C, mammaglobin-2, and LPHC. SCGB2A1 gene orthologs have been reported in the rat and chimpanzee species. Some SCGB2A1 antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. ELISA, Western Blot, and Immunofluorescence are also common applications.
