WebAffinity: "Affinity" simply refers to how strong the binding is (as judged by Kassociation or Kdissociation and ∆Go). "High affinity" refers to very strong binding (large negative ∆Go and a very small K d). The association or dissociation constant is often referred to as the "affinity” or “binding” constant.
