    摘要: 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.

    摘要: 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.
