WebWhat is the purpose of a Scatchard plot? When is it appropriate to use it and when is it not? To linearize the hyperbolic binding curve to obtain a more accurate measurement of KD (or KA) from the slope. It is appropriate to use it for non-cooperative binding, regardless of the number of ligands. Web1 day ago · The Scatchard plot is better than the Eadie–Hoffstee plot for binding data because it depends more on the values at high ligand concentration, the most reliable values.
