Abstract:
A magnetic chromatography method for performing a bioassay comprising the steps:a) providing a chromatographic medium;b) providing a magnetic field;c) providing a reaction mixture suspected of, containing an analyte, a reporter ligand that binds to said analyte, and a quantity of magnetic particles with capture ligands for binding said analyte immobilized thereon suspended therein;d) contacting said chromatographic medium with said reaction mixture such that said reaction mixture flows laterally across said chromatographic medium;e) applying said magnetic field at a site upon said chromatographic medium, said magnetic field being so applied such that a majority of said magnetic particles suspended within said reaction mixture is caused to become captured upon said medium at said site where said magnetic field is applied; andf) analyzing said majority of magnetic particle captured upon said chromatographic medium.
