ABSTRACT:
A humanized form of an anti-idiotype antibody to CEA, e.g., hWI2, has conserved immunoreactivity. The clinical benefits of anti-CEA antibodies are maximized by using the humanized anti-idiotype as a clearing agent for anti-CEA antibodies or antibody fragments. The humanized anti-idiotype also can be used as an immunogenic vaccine.
