Web13 feb. 2024 · IC50 of a drug is obtained by generating a dose-response curve and analyzing the drug-inhibitor interaction at different concentrations. Based on the plot of the dose-response curve, IC50 values are derived for specific inhibitors by determining the concentration required to reduce 50% of the maximum response from the drug. WebIC50 values can be determined in two ways; using curve fitting software, or by a point to point analysis. Curve Fitting: Several curve fitting software are commercially available: Graphpad Prism, Grafit CDC have developed a curve fitting software which is available from them directly Point to Point: This method uses in house excel templates.
