  • Methods for selective isolation of nucleic acids from microbial cells present in samples containing higher eukaryotic cells and/or tissues
    Patent number: 7893251
    Abstract: The invention relates to the use of nucleases, especially DNA-degrading nucleases, for degrading nucleic acids in the presence of one or several chaotropic agents and/or one or several surfactants. The invention further relates to a method for purifying RNA from mixtures of DNA and RNA as well as kits for carrying out such a method. Also disclosed is a method for specifically isolating nucleic acids from microbial cells provided in a mixed sample which additionally comprises higher eukaryotic cells as well as kits for carrying out such a method.
    Type: Grant
