US 6,071,395 A · Process and device for isolating nucleic acids

Abstract

Described is an apparatus for the contamination-free isolation of nucleic acids from biological fluids and suspensions containing nucleic acids comprising: a reaction compartment for holding an adsorption medium laden with nucleic acids; connected via a channel to a removal compartment; wherein the nucleic acids can be moved by an electrophoresis device from the reaction compartment into the removal compartment and enriched there; and the reaction compartment can be charged via a charging orifice and drained via a draining orifice being located essentially opposite of the charging orifice.
