NEDP1 KO U2OS cells are not resistant to treatment with camptothecin (CPT). WT U2OS and NEDP1 KO cells were plated in 96-well plates and treated with the indicated amount of CPT. 48 hours after exposure cell survival was measured using the CellTiterGlo assay. Graphs represent the mean ± S.E.M. of the percent survival compared to untreated cells.
