Simple statistical model of interaction between low-molecular weight immobilized ligands of the same
type and macromolecular receptors was considered. On example of the interaction of the immobilized
sulfamethoxazole with a selective antibody the adequacy of the proposed approach for establishment of
the dependence of adsorption capacity of the surface on the surface density of the immobilized ligand and
its charge state was shown using surface plasmon resonance.
