WebbIC 50 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%. [1] The biological component could be an enzyme, cell, cell receptor or microorganism. IC 50 values are typically expressed as molar concentration .
