Cheng-prusoff式
WebCheng-prusoff equation Definition: The Cheng-Pru soff equation defines the theoretical relationship between the IC 50 and K i of an inhibitory ligand.This is useful since the IC 50 changes depending on the amount of substrate in a reaction, however K i does not change as it is a direct measure of the relationship between the inhibitory ligand and its binding … The Cheng-Prusoff equation produces good estimates at high agonist concentrations, but over- or under-estimates K i at low agonist concentrations. In these conditions, other analyses have been recommended. See also.
