ISOLATION OF DNA MOLECULES USING MERCAPTO-ARYL LIGANDS

摘要

The present invention relates to a process for separating nucleic acid molecules, preferably open circular and supercoiled plasmid DNA and RNA molecules from each other, comprising the steps of providing a solution comprising the molecules; adsorbing the molecules to adsorbing groups on a carrier; and optionally washing the column with a suitable solution. The present process is especially suitable for large-scale isolation of supercoiled ccc DNA to be used in gene therapy.
