Mutation of the human neu protein facilitates down-modulation by monoclonal antibodies.


Amplification and overexpression of the neu gene have been found in several human adenocarcinomas. We have obtained monoclonal antibodies to the human neu protein by immunizing a Balb/c mouse with a Balb/c cell line expressing the human neu gene by transfection. The monoclonal antibodies reacted with neu protein on intact cells by immunofluorescence and… (More)
