Abstract: Provided herein are a preparation method and use of an anti-MET-and-RON bispecific antibody and an antibody-drug conjugate thereof. The anti-MET-and-RON bispecific antibody includes an anti-MET antibody fragment and an anti-RON antibody fragment which are linked to each other through a specific chemical “knobs-into-holes” structure.
Abstract: The present invention includes unique, isolated monoclonal antibodies that bind the PSI domain of human RON (RONPSI), and methods for making and using the same and novel combination therapies of anti-RONPSI antibodies, including humanized anti-RONPSI antibodies, nucleic acids that encode the heavy chain, the light chain, or both the light and heave chains of the antibody, host cells, expression vectors, and wherein the antibody or binding fragments thereof can be further conjugated with one or more cytotoxic or chemotherapeutic agents.
