EC50 - Wikipedia

WebBinding affinity refers to the strength of binding between a ligand and a receptor. It is important to keep binding affinity separate from things like efficacy and potency. Binding affinity does not predict efficacy or potency. Some full agonists have very high binding affinity, but so do some partial agonists, and so do many antagonists!
