| abstract |
The present invention relates to the use of a milled homogenate and/or a suspension and/or a cell lysate, stemming from a tumor resistant to at least one antitumoral compound in order to immunize and generate in vitro an antibody, or one of its functional fragments, directed against a tumoral antigen specifically expressed at the surface of said resistant tumor and being possibly involved in the resistance of said resistant tumor. n More particularly, the present invention is directed to such antibodies obtained by applying the method, such as the antibodies 1A6, 1A9, 2E11, 3C11 and 3G7, as well as to their use for treating cancer. |
