Cell-free protein synthesis is an attractive method for generating enzyme/protein variants for simplified functional analysis as both in vitro protein expression and analysis may often be performed in a single vial or well. Today, researchers may choose from multiple commercial cell lysate products or reconstituted systems which are compatible with either mRNA, linear DNA or plasmid DNA templates. Here we provide guidance for optimal design of the genetic elements within linear and plasmid DNA templates which are required to reliably practice cell-free protein synthesis. Protocols are presented for generating linear DNA templates, and data are presented to show that linear DNA templates may in many cases provide robust protein yields even when employing an Escherichia coli lysate for protein synthesis. Finally, the use of linear DNA templates makes it possible to bypass all cell cultivation steps and proceed from PCR amplification of synthetic DNA to generation of target protein in a matter of hours.
