The precise engineering of expression vectors using high-throughput In-Fusion™ PCR cloning

Abstract

In this chapter, protocols for the construction of expression vectors using In-Fusion™ PCR cloning are presented. The method enables vector and insert DNA sequences to be seamlessly joined in a ligation-independent reaction. This property of the In-Fusion process has been exploited in the design of a suite of multi-host compatible vectors for the expression of proteins with precisely engineered His-tags. Vector preparation, PCR amplification of the sequence to be cloned and the procedure for inserting the PCR product into the vector by In-Fusion™ are described. © 2009 Humana Press.
