概要	Scatchard analysis is a graphical method for determining ligand-receptor binding affinity (Kd) and binding capacity (Bmax) from binding data. Developed by George Scatchard in 1949, the Scatchard plot linearizes hyperbolic binding curves, enabling visual detection of multiple binding sites and quantitative parameter estimation.	Michaelis-Menten kinetics describes the rate of enzyme-catalyzed reactions as a function of substrate concentration. Developed by Leonor Michaelis and Maud Menten in 1913, this foundational framework models enzyme catalysis through the rapid-equilibrium approximation and enables prediction of drug metabolism rates in pharmacokinetics.	Schild analysis is a quantitative method for characterizing competitive receptor antagonism developed by Henry Schild in 1947. It uses dose-response curves in the presence and absence of antagonist to estimate the antagonist affinity constant (pA2), enabling standardized comparison of antagonist potency across drugs and experimental systems.
