MONOCLONAL ANTIBODY WHICH BINDS MET IN FORMALIN-FIXED AND PARAFFIN-EMBEDDED TISSUES AND RELATED METHODS

摘要

In a wide variety of human solid tumors, an aggressive, metastatic phenotype and poor clinical prognosis are associated with expression of the receptor tyrosine kinase Met. Disclosed herein are (a) a monoclonal antibody named Met4, which antibody is specific for Met, and (b) a hybridoma cell line that produces Met4. The Met4 antibody is particularly useful for detecting Met in formalin-fixed tissue. Methods of using the Met4 antibody for detection, diagnosis, prognosis, and evaluating therapeutic efficacy are provided.
