  • Amplification and detection of nucleic acids in blood samples
    Patent number: 5501963
    Abstract: This invention relates to a process for the amplification of nucleic acids in the form of DNA or RNA from blood samples by means of an enzymatic amplification method, characterized in that no preparation of the blood sample otherwise necessary to prepurify the nucleic acid to be amplified is performed and the proportion of the sample in the reaction mixture for the amplification process is greater than 5 volume % if a specific amount of salt is present in the reaction mixture. Depending on the proportion of blood sample and its salt contribution of monovalent and/or bivalent ions, the salt concentration in the reaction mixture in which the amplification is performed is, where applicable, adapted to the enzyme requirements by the use of an appropriately concentrated salt solution.
