Webconstant for an agonist would each provide an estimate of K app rather than K 1. This distinction is also important when considering those receptors (e.g., ligand-gated ion channels) that have more than one binding site for the agonist. B. Schild Equation and Plot—Further Detail The Schild equation is based on the assumptions that WebBinding affinity is the strength of the binding interaction between a single biomolecule (e.g. protein or DNA) to its ligand/binding partner (e.g. drug or inhibitor). Binding affinity is typically measured and reported by the equilibrium dissociation constant (K D ), which is used to evaluate and rank order strengths of bimolecular interactions.

What does the pD2 value of agonist indicate? Affinity or efficacy?

Web• If you have several concentrations of antagonist, use a different model that will directly fit the Schild model (using either X as concentration of agonist or X as the logarithm of the concentration of agonist) and determine the pA2. • If you want to test the null hypothesis that the EC50 ratio is 1.0 (no shift), that is easy to do.
