ABSTRACT:
Disclosed are methods and apparatus for performing highly sensitive enzyme-amplified assays using channel electrophoresis of an enzyme having a biorecognition moiety. Combining a binding reaction of an analyte and an enzyme having a biorecognition moiety, and an electrophoretic separation which uses enzyme-amplified detection methodology, assay methods and apparatus are provided that offer simplicity, quantitative sensitivity and rapid analysis. Also disclosed are highly sensitive catalytically-amplified assays using a capillary electrophoresis format in which the binding reaction prior to electrophoresis is heterogeneous or homogeneous, and direct or competitive. The methods and apparatus for conducting sensitive automated catalytically-amplified assays using electrophoresis may be conducted in a microscale format.
