Equilibrium binding assay
WebOne common technique for measuring protein-binding affinities uses flow cytometry to analyze ligand binding to proteins presented on the surface of a cell. However, cell … WebCreative Biarray uses equilibrium dialysis to determine the extent to which compounds bind to brain tissue. A semi-permeable membrane separates the compartment containing the compound in the brain homogenate from the compartment containing the compound in the buffer. The assay was performed at 37°C.
