title: A novel immunohistochemical technique for the detection of human oral carcinomas transplanted in nude mice using mouse monoclonal antibodies.
abstract: We have developed a new immunostaining technique specifically for the detection of human tumors transplanted into nude mice using mouse monoclonal antibodies (MoAbs) produced in our laboratory. The formation of a molecular complex consisting of three components (mouse MoAb or hybridoma supernatant, biotin-labeled anti-mouse immunoglobulins, and normal nude mouse serum) markedly reduced background staining and enhanced specific reaction with the transplanted tumors in nude mice. When MoAb production by electrofusion was screened with this new method, the incidence of hybridoma supernatant reactive with sections of transplanted tumor was 2.3 per 100 wells immunostained. These results suggest that production of MoAbs using transplanted tumors is immunohistochemically possible and that this method may provide a new means for developing useful tumor markers.
