Assay utilizing magnetic particles

P. Connolly (Inventor)

Research output: Patent

Abstract

An assay for the presence of an analyte or determining a biological or medical parameter comprising the steps of adding an assay component to a pH-sensitive material charged with magnetic particles, wherein the assay component causes a pH change which is a function of the analyte or parameter to be measured; subjecting the magnetic particles to an oscillating magnetic field; and measuring the effect of the magnetic field on the magnetic particles. The assay is an enzyme immunoassay. A kit for practicing the enzyme immunoassay is also described.
