Thirdly, if isolates are tested in duplicate, the replicate titrations in either the virus titration part, or the IC50 test should match. The resulting IC50values varied according to the parameter evaluated, whether percent inhibition or percent control was applied, and the computational IC50equation. IC50 represents the concentration at which a substance exerts half of its maximal inhibitory effect. The simplest estimate of IC50 is to plot x-y and fit the data with a straight line (linear regression).

It is used to guide lead optimization, build large-scale chemogenomics analysis, off-target activity and toxicity models based on public data. The IC50 is the concentration of an inhibitor where the response (or binding) is reduced by half. There is no firm definition of a resistant IC50. That is, the concentration of inhibitor required to reduce the biological activity of interest to half of the uninhibited value. Statistical analysis Data were collected and expressed as the mean standard deviation of three independent experiments and analysed for statistical significance from control, using the Dunnett test (SPSS 11.5 Statistics Software; SPSS, Chicago, IL). However, there are a number of ways that this concept of "half" can be interpreted.

IC 50 values were calculated on the basis of the analysis of single concentration-response curves. Seems simple enough.
