Non-uniformity in in vitro drug-induced cytotoxicity as evidenced by differences in IC values - implications and way forward.

Cell lines have proven indispensable for in vitro experiments and their utility as experimental models range from understanding the fundamental cell functioning to drug discovery. One of the most common utility of cell lines is for in vitro drug testing. Drug testing involves determining the cytotoxic effects of the drugs and such a measurement is expressed as the IC values of drugs.
