  • DNA polymerases having amino acid substitutions and homologs thereof
    Patent number: 6875573
    Abstract: Thermostable DNA polymerases both in native form and having single amino acid substitutions and optionally N-terminal deletions are disclosed. These polymerases exhibit a substantial improvement of DNA sequencing performance compared to Taq DNA polymerase. The instant DNA polymerases also possess improved salt tolerance.
    Type: Grant
    Filed: July 8, 2002
    Date of Patent: April 5, 2005
    Assignee: Amersham Biosciences Corp
    Inventors: Carl Fuller, Joseph Szasz

  • Thermostable alkaline phosphatases
    Patent number: 5939257
    Abstract: Enzymatically active thermostable alkaline phosphatases from Rhodothermus marinus, Thermus thermophilus, and Thermosipho africanus.
    Type: Grant
    Filed: October 25, 1996
    Date of Patent: August 17, 1999
    Assignee: Amersham Life Science, Inc.
    Inventors: Joseph Szasz, Maria Davis
  • Thermostable alkaline phosphatase of thermus thermophilus
    Patent number: 5633138
    Abstract: Alkaline phosphatase from Thermus thermophilus has been isolated. The enzyme has a pH optimum of greater than 10.5 and is stable to heating at 65.degree. C for 1 hour. The claimed invention relates to a method of detecting nucleic acids in a sample by providing a nucleic acid probe labelled with thermostable alkaline phosphatase from Thermus thermophilus; contacting the sample with said labelled nucleic acid; and detecting said nucleic acid in said sample by means of said thermostable alkaline phosphatase.
