Abstract
A method of assay for isotopically exchangeable analytes is disclosed. Analytes are labeled by enzymatic exchange of a hydrogen atom of the analyte and a deuterium or tritium atom. Preferably, analytes are labeled by reaction with an oxidant, a reducing agent which contains a deuterium or tritium atom, and an enzyme capable of catalyzing the reversible exchange of a hydrogen atom between the analyte, the oxidant, and the reducing agent. Kits for conveniently performing the assay methods are also disclosed.
