  • Publication number: 20130045894
    Abstract: 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.

  • Publication number: 20100075331
    Abstract: The present invention is directed to a method for analyzing the methylation status of a genomic DNA sample, comprising the steps of (i) fragmenting said sample and enriching said sample for sequences comprising CpG islands, (ii) generating a single stranded DNA library, (iii) subjecting said sample to Bisulfite treatment, (iv) clonally amplifying individual members of said single stranded DNA library by means of emulsion PCR, and (v) sequencing said amplified clonally amplified single stranded DNA library.

  • Patent number: 7429468
    Abstract: The present invention relates to thermostable mutants of B-type DNA polymerases comprising a Y-GG/A amino acid motif between the N-terminal 3?-5?-exonuclease domain and the C-terminal polymerase domain whereas the tyrosine of the Y-GG/A amino acid motif is mutated and whereas these mutant DNA polymerases are suitable for PCR.

  • Patent number: 7244602
    Abstract: 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.
