CellFree Sciences Co., Ltd.

It is our goal to make proteins work! CellFree Sciences is a Japanese company using its own wheat germ cell-free protein expression system to serve protein needs in life sciences and industrial R&D projects. Performing protein synthesis outside a cell in an in vitro system allows us to separate protein production from other processes required to maintain a cell. Working cell-free opens new opportunities to better adopt protein synthesis to protein needs offering dedicated conditions to make for example membrane proteins, labeled proteins for NMR, or well-folded antigens for antibody production. Our scalable and flexible expression system can serve protein needs from the small amounts used for production of our protein bead arrays presenting 23,000 human full-length proteins to individual proteins made on large-scale for use in structural biology, medical research, and diagnostic tests. Our plant-based expression system has a strong record on supporting a wide range of projects working on all kinds of proteins from the kingdoms of life.
