The standard dose-response curve is sometimes called the four-parameter logistic equation. 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 its midpoint. To extend the model to handle curves that are not … See more Create an XY data table. Enter the logarithm of the concentration of the agonist into X. Enter response into Y in any convenient units.
