This is a kit which is improved for the synthesis of extracellular secretory proteins such as cytokines and antibodies. This kit is suitable for the synthesis of stable isotope labeled disulfide-containing proteins.
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.


Stable isotope labeled amino acid mixtures are not included in this kit. Please use the separately sold stable isotope labeled amino acids mixtures. (Prod. No. 767972, 767964, and 771031)
This product may be available from bulk stock and can be packaged on demand. For information on pricing, availability and packaging, please contact Stable Isotopes Customer Service.

During recent years, the targets of protein structure analysis using nuclear magnetic resonance spectroscopy have become larger and more complicated. As a result, a complete and precise stable isotope labeling technique has been desired. A cell-free protein synthesis system is

Many important therapeutic targets are secreted proteins with multiple disulfide bonds, such as antibodies, cytokines, hormones, and proteases. The preparation of these proteins for structural and functional analyses using cell-based expression systems still suffers from several issues, such as inefficiency
