A monoclonal mouse antibody to human chorionic gonadotropin (hCG) was used in a modified unlabeled antibody enzyme-bridge staining method to demonstrate the localization of hCG in normal human placenta, pituitary gland, and six pituitary chromophobe adenomas. Mouse ascitic fluid containing monoclonal antibody could be diluted up to 1:500,000 for detection of hCG in the syncytiotrophoblast, whereas no staining was observed in the pituitary or adenomas even with high antibody concentrations (dilutions from 1:500 upward). Nonspecific background staining was negligible. These results demonstrate that monoclonal antibodies are suitable for immunohistochemical localization of antigens in tissues.
