The graph is representative for K562 cell line. Cell survival after exposure to IM, SPARC or their combination is showed. Cells were pre-treated with SPARC followed by IM for 24 h. Percentage of viable cells was measured by ATP.lite at 24 h and 48 h after addition of IM. Results represent the means of five independent experiments; error bars denote S.D.
