Abstract
The present invention provides a method and a system for the isolation and purification of nucleic acids from nucleic acid-containing material using a modified porous material containing cationic groups in a solid-liquid phase system. In some embodiments, the present invention is capable of obtaining nucleic acids with sufficient purity and quantity in a relatively simple way to enable accurate subsequent analysis or processing. In some embodiments, the liquid phase comprises an aqueous two-phase system (ATPS), comprising a first phase and a second phase, and the solid phase comprises a porous material, wherein the two phases travel through the porous material. In some embodiments, the nucleic acids enter the pores of the porous material and subsequently travel through the porous material while preferentially partitioning into one of the phases.
