Conditional homologous recombination of large genomic vector inserts

摘要

An efficient high throughput method for modifying genes in a recombination deficient host cell is disclosed. Such modifications include generating insertions, deletions, substitutions, and/or point mutations at any chosen site in the independent origin based cloning vector. The modified gene is contained in an independent origin based cloning vector that is used to introduce a modified heterologous gene into a cell. Such a modified vector may be used in the production of a germline transmitted transgenic animal, or in gene targeting protocols in eukaryotic cells.
