ABSTRACT:
An assay for detecting in a test sample, an analyte that undergoes auto-oxidation is disclosed. The assay comprises the steps of forming a reaction mixture by combining in an aqueous medium (i) a sample containing the analyte and (ii) a stabilizer that reduces the rate of radical mediated auto-oxidation of the analyte. The reaction mixture is incubated for a period of time and the rate of auto-oxidation is detected. When the detected rate of auto-oxidation is substantially zero, a sufficient quantity of an enzyme is added, that catalyzes the oxidation of the analyte. In the presence of the stabilizer, the analyte can be oxidized to a product species. The product species, the analyte, or both can be detected.
