Is ki the same as ic50
Witryna2 gru 2024 · This situation occurs when the concentration of competitor (usually denoted as IC50) is equal to KI X (1 + [L]/KD). The competitor's Kj can thus be calculated from the experimental IC50 value by the following equation (Cheng and Prusoff, 1973): [L] is known and KD is obtained from saturation binding experiments. Please note that Ki is … WitrynaThe best way to obtain errors for IC50 is to determine the IC50 values 3 or more times and determine the mean IC50 value and its standard deviation. If competitive inhibition is occurring and if the substrate concentration used is very much smaller than its Km then the IC50 value will equal the Ki for the competitive enzyme inhibitor.
