Cell-free protein synthesis: DNA in, protein out
A pipeline graphical abstract of cell-free protein synthesis. A DNA template goes into an open reaction — a cell extract or the reconstituted PURE system — which transcribes and translates it in one tube, with no cell wall or genome in the way, and a protein comes out within hours. Freeze-dried, the same reaction becomes portable for rapid prototyping, paper biosensors and on-demand production.

- Key result
- ~160 µg/ml/h in PURE batch (Shimizu et al. 2001); E. coli reactions scale 10 µL → 100 L, in-house extract ~$0.019/µL, freeze-dried extract keeps for months at room temperature (Gregorio et al. 2019)

Step by step
- DNA inA plasmid or linear DNA template encoding the protein of interest goes into the reaction (Gregorio et al. 2019)
- Open reactionA cell extract or the reconstituted PURE system (T7 RNA polymerase, 20 aminoacyl-tRNA synthetases, ribosomes, tRNAs, amino acids, energy) transcribes and translates it; no membrane or genome, so all the energy goes to the protein (Shimizu et al. 2001; Gregorio et al. 2019)
- Protein outProtein appears within hours — the PURE system makes ~160 µg/ml/h — and tagged factors are removed by affinity chromatography in ~1 h (Shimizu et al. 2001)
- UsesFreeze-dried and rehydrated, the reaction is portable: rapid prototyping of genetic circuits, paper biosensors with colour readouts, and on-demand therapeutics (Pardee et al. 2014, 2016)

Questions
What does the “Cell-free protein synthesis: DNA in, protein out” template show?
A pipeline graphical abstract of cell-free protein synthesis. A DNA template goes into an open reaction — a cell extract or the reconstituted PURE system — which transcribes and translates it in one tube, with no cell wall or genome in the way, and a protein comes out within hours. Freeze-dried, the same reaction becomes portable for rapid prototyping, paper biosensors and on-demand production.
What are the steps shown in “Cell-free protein synthesis: DNA in, protein out”?
1. DNA in: A plasmid or linear DNA template encoding the protein of interest goes into the reaction (Gregorio et al. 2019). 2. Open reaction: A cell extract or the reconstituted PURE system (T7 RNA polymerase, 20 aminoacyl-tRNA synthetases, ribosomes, tRNAs, amino acids, energy) transcribes and translates it; no membrane or genome, so all the energy goes to the protein (Shimizu et al. 2001; Gregorio et al. 2019). 3. Protein out: Protein appears within hours — the PURE system makes ~160 µg/ml/h — and tagged factors are removed by affinity chromatography in ~1 h (Shimizu et al. 2001). 4. Uses: Freeze-dried and rehydrated, the reaction is portable: rapid prototyping of genetic circuits, paper biosensors with colour readouts, and on-demand therapeutics (Pardee et al. 2014, 2016).
What are the starting materials and the product?
Starting materials: A DNA template (plasmid or linear) plus a cell extract or the PURE system. Product: A finished protein in hours, in an open tube — no living cell.
Which papers is “Cell-free protein synthesis: DNA in, protein out” based on?
