Open the CIPO recordAbstract From the Canadian patent
A novel method for producing recombinant polynucleotides in vitro is provided. This method entails the treatment of heteroduplex DNA sequences with a nuclease (preferably, DNase I) and a polymerase (preferably DNA polymerase , I), the enzymes primarily involved in nick translation. The results achieved using this process are superior to that achieved by previous in vivo recombination efforts utilizing specific DNA repair systems.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
