WebIC 50 values are typically expressed as molar concentration . IC 50 is commonly used as a measure of antagonist drug potency in pharmacological research. IC 50 is comparable … WebLinear vs. Log Graphs. As concentration increases, effect approaches a maximum, e.g. a blood vessel cannot dilate forever or it will explode! The maximum effect is called the Emax. The concentration at which the effect is 50% of the maximum is called the EC50. The shape of the linear graph is called a rectangular hyperbola. toxoplasmosis explained

WebA dose–response curve is a coordinate graph relating the magnitude of a dose (stimulus) to the response of a biological system. A number of effects (or endpoints) can be studied. The applied dose is generally plotted on the X axis and the response is plotted on the Y axis. In some cases, it is the logarithm of the dose that is plotted on the ...

Biological responses to ligand concentrations typically follow a sigmoidal function. The inflection point at which the increase in response with increasing ligand concentration begins to slow is the EC50, which can be mathematically determined by derivation of the best-fit line. While relying on a graph for estimation is more convenient, this typical method yields less accurate results and less precise. toxoplasmosis fatal
