The effect of adecatumumab on proliferation of breast cancer cell line and MCF-7 and normal breast epithelia line MCF10A. The respective cell lines were seeded at 104 cells and cell numbers determined daily for three days. A human IgG1 isotype mAb and a blank served as controls. a Results from triplicate determinations and standard deviations are shown. P values between isotype control and adecatumumab values were determined by Student`s t-test. b The effect of five anti-EpCAM mAbs on proliferation indices of MCF-7 and MCF-10A cell lines as percent of isotype control antibody determined by CyQUANT cell proliferation assay. Results from a representative experiment are shown.
