A new technique developed at UC Davis may have broken the barrier to rapid assembly of pure protein synthesis machinery outside of living cells.

In order to reconstitute cellular reactions outside of biological systems, scientists need to produce the proteins involved. Rapid yet high purity reconstitution of the cellular reactions is critical for the high-throughput study of cellular pathways and cell-free diagnostic tests for various diseases. Reconstituting cellular reactions outside cells, however, requires the separate expression and purification of each protein required to execute the reactions. This process is expensive and time consuming, making the production of more than several proteins at once extremely challenging.
The Molecular Prototyping and BioInnovation Laboratory, or “Biomaker Lab” at UC Davis is a place where students can try out their ideas and develop their own projects in biotechnology. It reflects as “maker culture” that is well-established in engineering, and growing in biological sciences.
