WebEC50 or the concentration of antibody that gives half-maximal binding is determined by direct and saturable binding of a rAB dilution series to both target antigen and a non-specific control protein. An estimate of affinity is interpreted from one-half the concentration at which rAB binding first achieves saturation. WebThe concepts of IC50 and EC50 are fundamental to pharmacology. The EC50 is the concentration of a drug that gives half-maximal response. The IC50 is the concentration of an inhibitor where the response (or binding) is reduced by half. Seems simple enough. But when you actually go to fit data to determine these values, there are several ...

WebAgonist affinity may be estimated in terms of the dissociation constant for agonist binding to a receptor using ligand binding or functional assays. It has, however, been suggested that measurements of affinity are always contaminated by efficacy so that it is impossible to separate the two parameters. WebI think that it is possible to use the concept of EC50 for a ligand binding assay, but the analysis must be done on a non linear curve ( linear-log, log-linear, or log-log), without … tst life time
