Stable-Isotope Labeling Using Cell-free Protein Synthesis

Cell free protein synthesis is a technology to synthesize proteins in vitro by cell extract supplemented with amino acids, target protein gene, and energy regeneration system. RIKEN's advanced E. coli based cell free protein synthesis technology is now available as Musaibo Kun kits. The kit enables rapid and easy protein synthesis with high isotope labeling efficiency.

* This product was developed with the support of the Japan Science and Technology Agency's "Industry-Academia Joint Seeds Innovation Project."

We highly recommend these kits for first trial. The kit can express intracellular proteins, secretory proteins, and membrane proteins. Proteins can be easily synthesized by adding template DNA and incubating for 1-16 hours because the reaction solution contains required components for protein synthesis including amino acids.

^*1 frGFP is synthesized with NHis tag and TEV protease recognition sequence attached to the N-terminus.　

^*2 Escherichia coli-derived alkaline phosphatase (BAP) is synthesized.

^*3 The Musaibo Kun N series cannot be used for the synthesis of stable isotope-labeled proteins.

^*4 The storage temperature of the the Musaibo Kun N series is -80 °C.

You can easily try cell-free protein synthesis. Six reactions of small-scale synthesis (0.1 mL) can be carried out with the included microdialysis cup. The kit is suitable for expression yield/solubility assay and reaction condition optimization.
