Half-maximal activity
WebNov 27, 2024 · The potency of a candidate enzyme inhibitor can be estimated by the decrease of the rate of an enzyme-catalyzed reaction. 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 … WebAnubha Bhonsle Journalist on Instagram: "# ...

WebNov 3, 2024 · where v is the rate, v max is the maximum possible rate, S is substrate concentration and K m is equal to the substrate concentration that gives half maximal activity. The derivation of this equation and its underlying assumptions may be found in any text book on enzyme kinetics. WebDose-response data are typically graphed with the dose or dose function (eg, log 10 dose) on the x-axis and the measured effect (response) on the y-axis. Because a drug effect is a function of dose and time, such a graph depicts the dose-response relationship independent of time. Measured effects are frequently recorded as maximal at time of ...
WebThe purpose of this study was to investigate whether exercise could induce calpain activation by altering the Ca2+ required for half-maximal activity (pCa50) and/or susceptibility of digestible muscle protein substrates. Rats (225 g) were assigned to control, exercise (25 m/min, 0% grade), and 24-h recovery groups. In this type of assay, a single concentration of radioligand (usually an agonist) is used in every assay tube. The ligand is used at a low concentration, usually at or below its Kd value. The level of specific binding of the radioligand is then determined in the presence of a range of concentrations of other competing non-radioactive compounds (usually antagonists), in order to measure the potency with which they compete for the binding of the radioligand. Competition curves may als…
