Magnetizable Solid-phase Supports for Purification of Nucleic Acids

Abstract

A simple, small scale non-hazardous procedure for the production of magnetizable solid-phase support (MSPS) beads has been developed based on the extrusion of agarose/iron oxide mixtures. The MSPS beads were derivatized using various amine ligands. Derivatized MSPS beads were used to adsorb nucleic acids from aqueous solution and to separate RNA/DNA mixtures.
