Recombineering: in vivo genetic engineering in E. coli, S. enterica, and beyond

Abstract

"Recombineering," in vivo genetic engineering with short DNA homologies, is changing how constructs are made. The methods are simple, precise, efficient, rapid, and inexpensive. Complicated genetic constructs that can be difficult or even impossible to make with in vitro genetic engineering can be created in days with recombineering. DNA molecules that are too large to manipulate with classical techniques are amenable to recombineering. This technology utilizes the phage lambda homologous recombination functions, proteins that can efficiently catalyze recombination between short homologies. Recombineering can be accomplished with linear PCR products or even single-stranded oligos. In this chapter we discuss methods of and ways to use recombineering.
