A dose-response curve graph on a laboratory computer display compares full agonist, partial agonist, and inverse agonist response curves plotted against log concentration.
A pharmacology textbook open to a chapter on receptor theory shows classical receptor occupancy equations by A.J. Clark alongside modern operational model equations.
A drug discovery research scientist examines a 3D molecular model of an opioid receptor on a high-resolution display, with candidate ligand docked in the orthosteric binding site.
A laboratory bench setup shows competitive binding assay equipment used to determine Ki values for antagonist compounds at adrenergic receptors in isolated tissue preparations.
A whiteboard in a pharmaceutical research facility shows a radioligand binding assay protocol, with steps for saturation binding, Scatchard plot analysis, and Bmax calculation.
A cellular biology laboratory incubator holds 96-well plates used in a high-throughput screening assay to identify novel agonist candidates for a specific receptor target.
A pharmacokinetics chart on a conference room projector displays comparative receptor binding kinetics for four opioid agonists, with kon and koff rates and resulting Kd values.
