Abstract
A method is provided for substantially increasing the dynamic range of an immunoassay and forestalling the hook effect observed with very large ligand concentrations in aqueous samples. The method comprises the addition of ligand binding partners which do not have labels associated therewith to compete with labeled ligand binding partners thereby effectively eliminating the presence of the excess ligand in the sample solution. The conversant method for ligand binding partner immunoassays is also provided.
