MURINE HYBRIDOMA AND DIAGNOSTIC ANTIBODY PRODUCED THEREBY

摘要

Hybridoma HB 8986 produces a murine monoclonal antibody which recognizes a new determinant expressed in bronchopulmonary carcinomas and A549 cell line derived tumors. Immunoperoxidase staining with the hybridoma on formalin fixed, paraffin embedded tissues shows that it specifically stains both the cytoplasmic and cell surface. The monoclonal antibody has the ability to distinguish preferably bronchopulmonary carcinomas with glandular differentiation from other bronchopulmonary carcinomas. Additionally, the monoclonal antibody may identify adenocarcinomas through the body.
