  • Patent number: 8008054
    Abstract: A purified thermostable enzyme is derived form the thermophilic archaebacterium Thermococcus gorgonarius. The enzyme can be native or recombinant, retains approximately 90% of its activity after incubation for two hours at 95° C. in the presence of stabilizing agents and possesses 3?-5? proofreading exonuclease activity. Thermostable DNA polymerases are useful in many recombinant DNA techniques, especially nucleic acid amplification by the polymerase chain reaction (PCR).
    Type: Grant

  • Publication number: 20050019789
    Abstract: A thermostable enzyme is provided which is derived from the microorganism Anaerocellum thermophilum. The enzyme has a molecular weight of 96 to 100 kDa, shows DNA polymerase activity and reverse transcriptase activity in the presence of magnesium ions. The enzyme may be native or recombinant, and may be used with selected primers and nucleoside triphosphates in a temperature cycling polymerase chain reaction on DNA or RNA as template with or without additional DNA polymerases as an enzyme mixture.
