iPE-Quick Kit ( 767824) is available and intended for the confirmation of target protein expression utilizing E. Coli extract before the use of this iPE kit.
This is a protein synthesis system that utilizes E. coli cell extract. It allows easy and efficient protein expression by adding circular or linear DNA as the template DNA, which enables transcription of mRNA with T7 RNA polymerase.
This kit has been developed under license from RIKEN, incorporating their proprietary, advanced cell-free protein synthesizing technology into a kit dedicated to stable isotope labeling.
This kit is not intended to be used for disulfide-containing proteins. For disulfide-containing proteins, refer to 797006.


For information on pricing and availability, please contact Stable Isotopes Customer Service.
Stable isotope labeled amino acid mixtures are not included in this kit. Please use separately-sold stable isotope labeled amino acids mixtures (prod. no. 767972, 767964, 771031).

A two-step PCR method has been developed for the robust, high-throughput production of linear templates ready for cell-free protein synthesis. The construct made from the cDNA expresses a target protein region with N- and/or C-terminal tags. The procedure consists only

Cell-free protein synthesis is suitable for stable-isotope labeling of proteins for NMR analysis. The Escherichia coli cell-free system containing potassium acetate for efficient translation (KOAc system) is usually used for stable-isotope labeling, although it is less productive than other systems.
