Article Abstract
Megaprimer-based polymerase chain reaction (PCR) strategies allow the versatile and fast assembly and amplification of a myriad of tailor-made or random DNA sequences readily available for conventional or restriction-free (RF) cloning.In this chapter, we present a megaprimer-based PCR protocol that enables the expeditious construction of customized fusion genes ready for cloning into commercial expression plasmids. With the expanding use of protein tag technology in the most diverse application fields, this protocol remains a versatile and affordable solution for the synthesis and fusion of peptide tags/domains of interest.

QuickStep is a cloning method that allows seamless point integration of a DNA sequence at any position within a target plasmid using only Q5 High-Fidelity DNA Polymerase and DpnI endonuclease. This efficient and cost-effective method consists of two steps: two parallel asymmetric PCRs, followed by a megaprimer-based whole-plasmid amplification. To further simplify the workflow, enhance the efficiency, and increase the uptake of QuickStep, we replaced the asymmetric PCRs with a conventional PCR that uses phosphorothioate (PTO) oligos to generate megaprimers with 3' overhangs.

The polymerase chain reaction (PCR) is the technique of choice used to obtain DNA for cloning, because it rapidly provides high amounts of desired DNA fragments and allows the easy introduction of extremities adequate for enzyme restriction or homologous recombination, and of artificial, native, or modified sequence elements for specific applications. In this context, the use of megaprimer-based PCR strategies allows the versatile and fast assembly and amplification of tailor-made DNA sequences readily available for cloning.In this chapter, we describe the design and use of a megaprimer-based PCR protocol to construct customized fusion genes ready for cloning into commercial expression plasmids by restriction digestion and ligation.

QuickStep-Cloning is a novel molecular cloning technique that builds upon the concepts of asymmetric PCR and megaprimer-based amplification of whole plasmid. It was designed specifically to address the major drawbacks of previously reported cloning methods. The fully optimized protocol allows for a seamless integration of a long DNA fragment into any position within a plasmid of choice, in a time-efficient and cost-effective manner, without the need of a tedious DNA gel purification, a restriction digestion, and an enzymatic ligation.

Background: Molecular cloning is an essential step in biological engineering. Methods involving megaprimer-based PCR of a whole plasmid are promising alternatives to the traditional restriction-ligation-based molecular cloning. Their widespread use, however, is hampered by some of their inherent characteristics, e.
