Discovery of high-affinity protein binding ligands--backwards

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. Web24 de jan. de 2024 · A high affinity interaction is commonly determined by a low dissociation rate (<10 -5 s -1) and a relative low equilibrium dissociation constant (<10 -9 M). Although a sufficient fast association rate enhances the forming of the complex, the dissociation rate determines the time that the two molecules stay together in complex. sharon ann jackson winchester tn
