The ic50
WebIC50 is a quantitative measure that indicates how much of a particular inhibitory substance (e.g. drug) is needed to inhibit, in vitro, a given biological process or biological component by 50%. The biological component could be an enzyme, cell, cell receptor or microorganism. IC50 values are typically expressed as molar concentration.

WebIC50 Calculator IC 50 represents the concentration at which a substance exerts half of its maximal inhibitory effect. This value is typically used to characterize an antagonist of a … WebThe EC50 (or IC50) refer to a concentration of agonist (or antagonist) required to increase (or reduce) the measured response to half - or 50% - of its maximal value. However, there …
WebSince the concept of the half maximal inhibitory concentration (IC50) is used extensively for studying reversible inhibition enzymatic reactions, it is important to clearly understand the experimental design and the mathematical modeling … WebThe simplest estimate of IC50 is to plot x-y and fit the data with a straight line ( linear regression ). IC50 value is then estimated using the fitted line, i.e., Y = a * X + b, IC50 = (0.5 - b)/a. Log transformation Frequently, linear regression is …
