Determining the parameters for receptor-ligand interaction by serial dilution method for the case when the ligand and receptor are in a pre-existing mixture



Determining the parameters for receptor-ligand interaction by serial dilution method for the case when the ligand and receptor are in a pre-existing mixture



Ukrains'kyi Biokhimichnyi Zhurnal 77(4): 138-145



New methods of determining the binding parameters for ligand-receptor interaction are considered. The considered approaches are based on the earlier suggested method of serial dilution and application of so-called coordinates of dilution. It was shown that the suggested methods allow to evaluate affinity constant and ligand concentration even for the case, when the receptor and corresponding ligand of unknown concentration are in a mixture and their separation from each other is impossible. In this connection the suggested methods are especially useful for studying the ligand-receptor interaction if the receptor is very liable and its purification from the ligand would cause drastic changes of its binding properties.
