Method of constructing vectors for homologous recombination directed mutagenesis

摘要

The present invention provides a novel vector system and thereby a novel method for the simplified construction of recombinant vectors for directed mutagenesis. Said vector system is used to modify the eukaryotic genome, particularly of embryonic stem cells, at precise and predefined loci by the means of homologous recombination. Further more, said system finds its usage in the generation of new strategies for gene therapy and in the generation of genetically modified higher eukaryotic organisms.
