Cell-free protein synthesis has emerged as powerful alternative to cell based protein expression for functional and structural proteomics. The TNT^® SP6 High-Yield Protein Expression System uses a high-yield wheat germ extract supplemented with SP6 RNA polymerase and other components. Coupling transcriptionaland translational activities eliminates the inconvenience of separate in vitro transcription and purification steps for the mRNA, while maintaining the high levels of protein expression (1).
