WitrynaIC 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 biological process (ex. phosphorylation). In pharmacology, it is an important measure of potency for a given agent. Traditionally, this value is expressed as a molar concentration. WitrynaHalf maximal effective concentration ( EC50) is a measure of the concentration of a drug, antibody or toxicant which induces a response halfway between the baseline and maximum after a specified exposure time.
