Expression vector system and a method for optimization and confirmation of DNA delivery and quantification of targeting frequency

摘要

An expression vector system comprising a pair of expression vectors constructed from a wild-type and a mutant version of a maker, reporter or selection gene, and a method for optimization and confirmation of DNA delivery and of gene targeting and for quantification of targeting frequency. Novel prokaryotic/eukaryotic DNA vectors used for DNA delivery and gene targeting assessment and targeting frequency quantification.
