ABSTRACT
Methotrexate (MTX)was linked covalently to monoclonal IgG antibody (AU_(14-1)) to a mouse uterine cervical cancer with the use of dextran T-40 as the intermediate carrier. The molar ratio of IgG MTX was 1 20 in the conjugate. The conjugate retained full antibody binding activity at the AU_(14-1) concentration of 3.75?10~(-8) M measured by an indirect membrane immunofluorescence assay. The in vitro experiments confirmed that the conjugate not only showed target-selective antitumor effecacy but also was proved to be more effective in inhibiting the growth of HeLa cells than the effect of U_(14) cells, so that it confirmed the "evolutionary antigen" theory. It is suggested that AU_(14-1)-Dex-MTX conjugate may have good potentiality in clinical application.
