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 and a quantity of magnetic particles suspended therein which are capable of forming a complex with said analyte; d) contacting said chromatographic medium with said reaction mixture at a site thereon such that said reaction mixture flows bi-laterally across said chromatographic medium; e) applying said magnetic field at said site upon said chromatographic medium corresponding to where said reaction mixture is contacted in step d), said magnetic field being so applied such that a majority of said magnetic particles suspended within said reaction mixture are caused to become captured upon said medium as said site; and f) analyzing said magnetic particles captured upon said chromatographic medium for the presence of said analyte.
