Binding of a ligand to a receptor

WebMay 13, 2024 · When conducting binding experiments one should distinguish between specific and nonspecific binding of the ligand . While specific binding (SB) implies association of the ligand exclusively with the target receptor, nonspecific binding (NSB) results from the labeled ligand binding to the other components present in the assay … WebIf concentrations of the endogenous ligand are really low, then a partial agonist will increase receptor activation, functioning as a weak agonist. In contrast, if concentrations of endogenous ligand are high, the partial agonist will compete for receptors and bind to a certain proportion of receptors previously bound by endogenous ligand.

WebThe ligand binding causes the conformational changes of receptor and ion channel forming. The binding of Ach to each of four subunits of AchR induces change in receptor and opening the sodium selective channel through the centre of the receptor protein. It causes the depolarisation of surrounding membrane.
