The IC50. In many experiments, you vary the concentration of an inhibitor. With more inhibitor, the response decreases, so the dose-response curve goes ...

It fits the logIC50, which is not the same as the Ki of the unlabelled ligand for binding. The Ki depends on the IC50, the concentration of radioligand, and its ...

The only difference is that the inhibitory equations fit the IC50 ("I" for inhibition) while the stimulation equations fit the EC50 ("E" for effective). If ...

You have a choice, in the Confidence tab, to either mark selected parameters as "unstable", to mark entire fits as "ambiguous", or neither.

It fits four parameters: the bottom and top plateaus of the curve, the EC50 (or IC50), and the slope factor (Hill slope). This curve is symmetrical around ...
