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.

WebThe guidelines first describe how to decide whether to use the relative EC50/IC50 or the absolute EC50/IC50. Assays for which there is no stable 100% control must use the relative EC50/IC50. Assays having a stable 100% control but for which there may be more than 5% error in the estimate of the 50% control mean should use the relative EC50/IC50. WebYou'd need at least two values, one to quantify the middle of the curve (the drug's potency) and one to quantify how low it gets (the drug's maximum effect). The graph above shows two definitions of the IC50. The relative IC50 is by far the most common definition, and the adjective relative is usually omitted.

WebSubramaniyam Ravichandran. IC50 is the inhibitory concentration. It is the concentration which inhibits growth of 50% of the test organisms. Therefore, you will need to draw a graph of concentration on X-axis vs. percentage inhibition on Y-axis, as the Pushpinder Kaur suggested. The slope of this graph will give you the IC50 value. geometric candle holder hobby lobbyWebBeware of using a linear trendline, if your inhibition profile is not linear this will give you messed up values.
