    Abstract: Described is a method of isolating cell components, such as nucleic acids, from natural sources by filtering a sample of the digested natural sources such as cells or cell fragments. The method is characterized in that the sample is passed through a filter, the pore size of which decreases in the direction of flow of the sample through the filter.

    Abstract: A filtration process for the preparation of nucleic acids from natural sources is disclosed. The sources containing nucleic acids are lysed; the lysate is left to rest for some time; the resulting lysate passes a filter layer. The filter layer is selected from silica gel, aluminum oxide or packed diatomaceous earth, or interwoven or cemented non-wovens of glass fibers and silica gel. Other filter layers include cellulose, paper, compressed paper, and paper non-wovens. The fraction leaving the filter layer is then collected and the nucleic acid is subsequently isolated and purified from the collected fraction. Furthermore, the filter layer has not been modified with anion exchange groups.
