Publication number: 20130045894Abstract: The present invention is a method for amplification of target nucleic acids wherein a first and second primer set is used to amplify a target nucleic acid in a single amplification reaction. The primers of the first primer set generate a first amplification product that serves as a template for amplification by the primers of the second primer set due to the incorporation of a first and second tag sequence added to the target nucleic acid from the forward and reverse primers of the first primer set to which the primers of the second primer set can hybridize to its complement. Additional sequences are thereby added to the resulting target nucleic acid amplicons because of further amplification from the first amplification products by the primers of the second primer set.Type: ApplicationFiled: August 15, 2012Publication date: February 21, 2013Inventors: Bruno Frey, Irene Labaere

Patent number: 7244602Abstract: The invention concerns polymerase chimeras which are composed of amino acid fragments representing domains and which combine properties of naturally occurring polymerases that are advantageous with regard to a particular application. It has surprisingly turned out that the domains from the various enzymes are active in the chimeras and exhibit cooperative behavior. In addition the present invention concerns a process for the production of the chimeras according to the invention and the use of these chimeras for the synthesis of nucleic acids e.g. during a polymerase chain reaction. Moreover the present invention concerns a kit which contains the polymerase chimeras according to the invention.Type: GrantFiled: June 6, 2003Date of Patent: July 17, 2007Assignee: Roche Diagnostics GmbHInventors: Bruno Frey, Britta Villbrandt, Dietmar Schomburg, Harald Sobek, Waltraud Ankenbauer
