A technique that could be used to measure directly the affinity of an agonist at muscarinic acetylcholine receptors is: A radioligand binding assay. -can provide the Kd value for a drug. This tells use the affinity (tightness of binding). -We can also measure the maximum binding (Bmax) which can tell ... Examples of important contributions made using this technique include: • The 1921 discovery by Otto Loewi of Vagusstoff using frog hearts resulted in the identification of acetylcholine as the first neurotransmitter. • Enkephalin using bioassays such as the mouse vas deferens as a bioassay. coach daily
