Table 2 Table of IC50 values for each parental and RR cell line up to 144 h post-exposure to radiation. If no value is recorded this indicates that a reduction in proliferation by 50% at that time point had not occurred; MCF-7 and MDA-MB-231 cell lines were evaluated up to 120 h post radiation whereas ZR-751 cell line was evaluated up to 144 h post radiation
