General method for the modification of different BAC types and the rapid generation of BAC transgenic mice

Abstract : Most genome projects have relied on the sequencing of bacterial artificial chromosomes (BACs), which encompass 100-300 kb of genomic DNA. As a consequence, several thousand BAC clones are now mapped to the human and mouse genome. It is therefore possible to identify in silico a BAC clone that carries a particular gene and obtain it commercially. Given the large size of BACs, most if not all regulatory sequences of a gene are present and can be used to direct faithful and tissue-specific expression of heterologous genes in vitro in cell cultures and in vivo in BAC-transgenic mice. We describe here an optimized and comprehensive protocol to select, modify, and purify BACs in order to generate BAC-transgenic mice. Importantly, this protocol includes a method to generate, within 2 days, complex plasmid cassettes required to modify BACs, and to efficiently modify different types of BACs selected from the two major BAC libraries available. Altogether, using a combination of genomic database analysis, overlap PCR cloning, and BAC recombination in bacteria, our approach allows for the rapid and reliable generation of "pseudo knockin" mice. genesis 38:39-50, 2004.
