Title: Process for nucleic acid hybridization and amplification
Inventor: ZARLING DAVID A
IPC: C12Q1/68
Filed: 1991-04-17
Abstract: The present invention is directed to a method of achiev-ing RecA protein facilitated amplification of a double-stranded DNA target sequence having first and second complementary strands, each strand with 5' and 3' ends. The method involves complexing a primer complementary to a 5' end region of the first strand and a primer complementa-ry to a 5' end region of the second strand with RecA pro-tein in the presence of ATP-y-S. The complexed primers are then reacted in a mixture also containing the target se-quence, all four dNTPs, RecA protein and DNA polymerase.      The reaction is conducted below the temperature required for thermal dissociation of the two target strands and continued until a desired degree of amplification of the target sequence is achieved.      The present invention further includes the cloning and identification of the coding sequences for the RecA protein of Thermus aquaticus.

Title: Enzymes and their use
Inventor: COBBS CARRINGTON S
IPC: C12N11/08
Filed: 1990-06-01
Abstract: ABSTRACT OF THE DISCLOSURE         A lipase or lipase isozyme from Candida rugosa is used to stereoselectively hydrolyze esters, esterify acids or transesterify esters in aqueous/organic systems.  Esters of 2-substituted acids such as 2-(4-hydroxyphenoxy) propionic acid, where the acid is not substituted at the 2-position with halogen, are hydrolyzed at high enantiomeric excess in the presence of an organic solvent.  A reducing agent may be present to prevent oxidation of the acid and its esters.  Two lipase isozymes are purified from Candida rugosa by ion exchange chromatography or isoelectric focusing, and are used for stereoselective hydrolysis of esters, esterification of acids or transesterification of esters.  The lipase or lipase isozyme may be immobilized, and immobilization is improved by the presence of polyvinyl alcohol or an organic acid such as stearic acid.  The presence of a fatty acid or fatty acid ester during lipase reaction increases the rate or stereoselectivity of the reaction.
