Express Protein from PCR Fragments or Plasmid DNA
The TnT® Quick Coupled Transcription/Translation Systems provide convenient single-tube, coupled transcription/translation reactions for eukaryotic cell-free protein expression. These in vitro translation systems combine the RNA Polymerase, nucleotides, salts, amino acids and Recombinant RNasin® Ribonuclease Inhibitor with the reticulocyte lysate solution to form a single TnT® Quick Master Mix.
The TnT® Quick Coupled Transcription/Translation System is available in two configurations for the expression of genes cloned downstream from either the T7 or SP6 RNA polymerase promoters. To use these cell-free protein expression systems, 0.2–2.0μg of circular plasmid DNA containing a T7 or SP6 promoter, or a PCR-generated fragment containing a T7 promoter, is added to an aliquot of the TnT® Quick Master Mix and incubated in a 50μl reaction volume for 60–90 minutes at 30°C. The expression reaction produces significant quantities of protein for a variety of applications including GST pull-downs and gel shift assays.
These mammalian-based systems express soluble, functional proteins that are post-translationally modified, unlike E. coli-based systems. Expressed proteins can be used directly after expression; no additional protein purification needed.

Applications of In Vitro Translation Systems
The TnT® Transcription/Translation Systems provide a simplified and accelerated method to perform in vitro protein translation. These systems have proven to be useful for many downstream applications including, but not limited to, glutathione-S-transferase (GST) pull-downs, gel shift assays, co-immunoprecipitation, characterization of protein modifications, protein:protein and protein:nucleic acid interactions and protein activity studies.
The animations and article below discuss a few of these applications in more detail. For more information about in vitro protein translation systems and how they can be used, see the Protein Expression chapter of the Protocols & Applications Guide.

protein translation. These systems are useful for many downstream applications,
including protein:protein interactions and protein:DNA interactions.
In this article, we review several publications that utilized TnT® Systems and
explore how these systems can be employed beyond these initial protein
translation applications.
