METHOD OF SEPARATION OF DEOXYRIBONUCLEIC ACIDS

摘要

The present invention relates to a method of separating nucleic acids from a liquid, which comprises providing a mobile phase comprising nucleic acids and a first salt, which forms lyotropic ions when dissolved; passing said mobile phase across a hydrophobic interaction chromatography (HIC) matrix to adsorb deoxyribonucleic acid(s); passing an eluent across said matrix to desorb one or more deoxyribonucleic acid(s), which eluent comprises the first salt as well as an increasing gradient provided by a second salt, which second salt forms less lyotropic ions when dissolved than the first salt; and isolating at least one fraction comprising separated deoxyribonucleic acid(s).
