ABSTRACT:
The present invention establishes a simple and a highly sensitive detection method for hEPR and provides a novel detection method for human tumors which express hEPR. In particular, the present invention provides a monoclonal antibody which specifically recognizes human epiregulin (hEPR), hybridoma which produces the monoclonal antibody, and a highly sensitive detection method for hEPR using the monoclonal antibody.
