Patents by Inventor Volker Leitenberger

Volker Leitenberger has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Stabilized aqueous nucleoside triphosphate solutions
    Patent number: 6916616
    Abstract: The invention concerns stable aqueous solutions containing one or several nucleoside triphosphates wherein the respective solution has a pH value of more than 7.5 and contains no additional substances with a stabilizing effect. The nucleoside triphosphate solutions are used in particular for DNA synthesizing reactions such as e.g. RT-PCR, cycle sequencing, random priming and nick translation. One of the most important applications of such solutions containing deoxy-nucleoside triphosphates (d-NTP) is their use in the polymerase chain reaction (PCR).
    Type: Grant

    Date of Patent: July 12, 2005
    Assignee: Roche Diagnostics GmbH
    Inventors: Hans-Georg Ihlenfeldt, Axel Schmidt, Klaus Muhlegger, Volker Leitenberger
