Another version of this pharmaceutical is such that the above antibody is conjugated with a cytotoxic agent(e.g. maytansinoid, calicheamicin). A kit including an immunohistochemically analytical means that diagnoses the presence of tumor using the above antibody is also provided. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
