Successful Transcription/Translation with a Variety of Templates

The E. coli S30 Extract System for Linear Templates is prepared using minor modifications of the protocol described by Lesley and colleagues and allows successful transcription/translation of linear DNA templates. The investigator need only provide linear DNA containing a prokaryotic E. coli-like promoter (such as lacUV5, tac, λPL (con) and λ-PR). A ribosome binding site is required to direct the synthesis of proteins in vitro. In vitro-generated RNA from DNA templates lacking an E. coli promoter may also be used in this system, but protein yields will be decreased to 1–10% of that produced from linear DNA templates.

The E. coli S30 Extract System for Linear Templates allows the use of many different templates, including DNA fragments, PCR-synthesized DNA, ligated overlapping oligonucleotides, in vitro-generated RNA and prokaryotic RNA. The use of this system reduces the chance of expressed proteins degrading.
