Abstract

Targeting vectors for embryonic stem (ES) cells typically contain a mouse gene segment of >7 kb with the neo gene inserted for positive selection of the targeting event. More complex targeting vectors carry additional genetic elements (e.g. lacZ, loxP, point mutations). Here we use homologous recombination in yeast to construct targeting vectors for the incorporation of genetic elements (GEs) into mouse genes. The precise insertion of GEs into any position of a mouse gene segment cloned in an Escherichia coli/yeast shuttle vector is directed by short recombinogenic arms (RAs) flanking the GEs. In this way, complex targeting vectors can be engineered with considerable ease and speed, obviating extensive gene mapping in search for suitable restriction sites.
