Why the Myth of High and Low Affinity Binding Sites Could Be Slowing Your Pipeline   If you’re working The interpretation of high and low affinity binding sites  on GPCRs.   High and Low Affinity: What’s Really Going On? In many systems, a ligand may appear to bind with very high affinity when it facilitates formation of ligand-receptor-G protein complexes —an observation that creates the illusion of multiple sites.  

In this exclusive Expert Drug Hunter lesson, Terry Kenakin dismantles 100 years of receptor theory and Discover how receptors actually behave, how ligands uniquely sculpt their function, and how cryptic allosteric
