Did you know?
WebHalf maximal inhibitory concentration, or IC 50, is a measurement representing the halfway point in which a compound of interest produces complete inhibition of a biological or biochemical function. This information is derived based on pharmacological data in reference to a dose-response curve. WebNov 27, 2024 · The concentration of an inhibitor capable of causing the decrease of enzyme activity by 50%, under specified assay conditions, is called the half-maximal inhibitory concentration (IC 50 ). In other words, the IC 50 value indicates how much of an inhibitor is needed to inhibit the activity of a given enzyme by half.
WebOct 1, 2024 · The resistance of GC cells to DDP was evaluated at half maximal inhibitory concentration (IC50). AGS, AGS/DDP, MKN45, and MKN45/DDP cells were cultured in the absence or presence of different levels of the DDP (0.1, 1, 5, 10, 20, 40, 80, and 160 μM) for 72 h. Cell viability was measured by MTT assay kit (Sigma). WebOct 25, 2016 · Inconsistencies in the half-maximal (50%) inhibitory concentration (IC50) data for anticancer chemotherapeutic agents have yielded irreproducible experimental results and thus reciprocally contradictory theories in modern cancer research. The MTT assay is currently the most extensively used method for IC50 measurements.
