US Patent 7682786 Modulation of the binding properties of nucleic acid binding partners

A method for specifically determining the presence of a target by contacting said target in the presence of other targets with a probe capable of binding to said target to form a complex of said target with said probe, wherein the contacting is performed in the presence of a compound enhancing the specificity of said binding or the complex formed is contacted with a compound enhancing the specificity of said binding. This method opens the way to a better discrimination between related nucleic acid sequences in diagnostic assays.
