Cell-free systems & cell-free bioproduction
Cell-free protein synthesis (CFPS) bypasses the living cell: ribosomes and translation factors in a reaction tube deliver the target protein in hours, not weeks, with toxic and non-canonical amino acids incorporated.
1 · What it gives
Cell-free systems (Cell-Free Protein Synthesis, CFPS) are a paradigm that dispenses with the living host cell in industrial synthesis: only the molecular translation machines (ribosomes, tRNAs, initiation/elongation/termination factors) are extracted from organisms and assembled in a reaction tube with a DNA template, amino acids and an ATP-regeneration system. A living cell spends up to 80% of its resources on its own metabolism; a cell-free system directs all activity to the product, cutting synthesis from weeks to hours and enabling proteins toxic to cells as well as non-canonical amino-acid incorporation.
Key platforms of cell-free production:
- Cell-lysate CFPS (Cell Lysate CFPS): E. coli, CHO, wheat-germ extracts — a ready translation complex.
- Reconstituted PURE (PURE): 36 purified E. coli enzymes, no endogenous proteases — absolute purity.
- Enzymatic cascades (Cell-Free Cascades): 10–20 thermostable enzymes turn sugars into chemicals without a cell.
- Paper sensors (Paper TX-TL): lyophilised TX-TL + riboswitches for field diagnostics.

- Non-canonical amino acids (nSAA): re-assigning tRNA/synthetases to incorporate artificial amino acids (ADC, click chemistry).
- Continuous-flow microfluidic reactors: continuous substrate feed and inhibitor removal — day-long synthesis.
