US Patent:

6875573, Apr 5, 2005
Filed:

Jul 8, 2002
Appl. No.:

10/190967
Inventors:

Carl Fuller - Berkeley Heights NJ, US
Joseph Szasz - Chardon OH, US
Assignee:

Amersham Biosciences Corp - Piscataway NJ
International Classification:

C12Q001/68
C07H021/04
US Classification:

435 6, 536 231, 536 243, 536 2433, 530350
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.

US Patent:

56331380, May 27, 1997
Filed:

May 30, 1995
Appl. No.:

8/452988
Inventors:

Maria Davis - Twinsburg OH
Joseph Szasz - Chesterland OH
Assignee:

Amersham Life Science, Inc. - Cleveland OH
International Classification:

C12Q 168
C07H 2104
US Classification:

435 6
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.
