Claim Text:
1. A method for purifying target biomolecules from an aqueous phase, or for analyzing whether an aqueous phase contains target biomolecules, the method comprising: (a) providing a vessel comprising an aqueous phase containing magnetic particles and possibly target biomolecules, wherein the aqueous phase is overlaid with an organic phase and wherein target biomolecules present in the aqueous phase bind to the magnetic particles; (b) guiding a magnetic rod through the organic phase; (c) binding the magnetic particles to the magnetic rod, wherein the magnetic articles are not fixed to a side of the vessel by a magnet prior to the binding; (d) removing the bound magnetic particles from the aqueous phase by passing the magnetic rod and the bound magnetic particles through the organic phase, thereby displacing any aqueous phase from the magnetic particles so as to prevent carry-over of the aqueous phase; and (e) when the method is for analyzing, further comprising analyzing whether the target biomolecules are present.
