Abstract
A solid substrate is simultaneously contacted with a labeled form of a ligand to be assayed, a receptor for the ligand to be assayed and a solution of an ionic salt to produce a solid substrate which contains the labeled form of the ligand and the receptor. In a subsequent assay for the ligand, the solid substrate is contacted with a sample containing the ligand, whereby the labeled form of the ligand is available for equilibration with the receptor in competition with the ligand to be assayed.
