Protein production technologies in a \u201ccell-free\u201d system consist of using cell extracts (or lysates) containing all the natural machinery of transcription and translation, to produce, in-vitro (in a tube, a flask, a bioreactor etc), one or several biomolecules of interest for the pharmaceutical industry, the diagnostic sector, the synthetic biology, the food industry and more generally for the bioeconomy.<\/p>\n

These systems are the most commonly used because they enable the best productivity in terms of expression (several mg\/mL for some proteins) at the lowest cost. They are also easier to implement. Their main limitation is that they do not perform post-translational modifications (glycosylation, phosphorylation etc.) except for the establishment of disulfide bridges. However, these modifications can be achieved through the incorporation of amino acids carrying these modifications or in post-production by chemical couplings.<\/span><\/p>\n

A growing number of cell-free systems based on eukaryotic lysates have been developed in recent years to produce complex proteins. They have the advantage of performing post-translational modifications often required for the activity of proteins of pharmaceutical interest. The diversity of eukaryotic systems developed for cell-free expression means that the best and most suitable system can be identified resulting in the high-quality production of the protein of interest. The disadvantage of such systems remains their expression yields, which are lower than cell-based systems and prokaryotic cell-free systems for many proteins.<\/span><\/p>\n

This system is marketed under the term \u201cPURE system\u201d. Its base is not made up of a cell extract, but of the assembly of the 36 proteins necessary for the transcription steps of a gene into mRNA and then of the translation of this mRNA into protein. This system has the advantage of obtaining a relatively pure product before any purification stage. It also allows the precise ratio modulation of the different components of the production machinery and a better understanding of their respective influence. This system can be compared to the \u201cprecision clockwork\u201d of cell-free technologies. It is used for small-scale expression because it remains expensive and often offers low yields.<\/span><\/p>\n
