In this session, you’ll gain:   ✅ A framework for understanding when apparent multiple affinities really Every day spent misunderstanding the meaning of apparent affinity differences can slow your project’s The interpretation of high and low affinity binding sites  on GPCRs.   High and Low Affinity: What’s Really Going On? It’s common to observe two apparent affinities for a ligand under certain experimental conditions.

As 2025 comes to a close, this final edition of Weekly News focuses on how GPCR binding affinity experiments Terry’s Corner: GPCR Binding Affinity Experiments That Hold Up Orthosteric GPCR binding affinity experiments Yet small design choices—often treated as technical details—quietly reshape the affinity you think you estimates , leading to false confidence in Ki values derived from GPCR binding affinity experiments. Design GPCR binding affinity experiments that tell the truth , ensuring affinity data support—rather

It is also a matter of G protein coupling, tissue context, and the signaling assay used to measure affinity Affinity is not a fixed property - it is assay-dependent The apparent affinity of adenosine for its own A cAMP assay and a binding assay using the same receptor and the same ligand can return different affinity " and "high affinity" are assigned across the A2A and A2B subtypes. 4. differences, tumor microenvironment, and immune escape 22:08 Why affinity measurements shift depending

Terry Kenakin shows how tuning receptor expression separates affinity from efficacy, unmasks hidden agonism functional volume control, the deliberate tuning of system sensitivity, as a way to separate a ligand's true affinity Terry Kenakin will show how reducing sensitivity lets you measure affinity and relative efficacy and The same approach distinguishes what an allosteric modulator does to affinity versus efficacy, including From the Assay to the Candidate Reduce sensitivity and affinity separates from efficacy, so system-independent

How receptor residence time — not affinity — rescued a CRF drug discovery program, and why a career in Sam Hoare: Receptor Residence Time and GPCR Data Analysis For most of GPCR pharmacology's history, affinity But affinity is a snapshot. The Off-Rate That Saved a Program Standard binding assays showed identical affinity. Across multiple programs — including work on a vesicular transporter where in vitro affinity at pH 7.4
