  • Method for cell lysis and PCR within the same reaction chamber
    Patent number: 9090926
    Abstract: A method for amplification of a target DNA, comprising the steps of (i) transferring a liquid with a first volume comprising at least one or more living cells into a vessel (ii) adding to said vessel a PCR reaction buffer with a second volume, whereas said second volume is at least 2× as large as said first volume (iii) lysing said at least one or more living cells within said vessel by means of incubation for at least 1 Minute at at least 90° C., and (iv) amplifying said target by means of a polymerase chain reaction without performance of an intermediate purification step.
