Patents by Inventor Sigridur Hjorleifsdottir

Sigridur Hjorleifsdottir 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).

  • Publication number: 20080311626
    Abstract: The invention provides novel strand displacement DNA polymerases which can be used in a rapid and efficient strand displacement amplification reactions. The polymerases are significantly more thermostable than prior art polymerase and retain high activity at elevated temperatures. Also disclosed are genes encoding the polymerases and vectors comprising the genes. Representative polymerases of the invention are obtainable from bacterial strains of the species Thermus antranikianii and Thermus brockianus and also from environmental samples with isolation of the source species.
