Cell-free extracts have been researched and continuously streamlined for around 50 years. It is believed that these extracts work best when routinely obtained from exponentially growing cells to capture the most active translation system. Here we report on an active cell-free extract derived from E. coli A19 that was harvested under nongrowing, stressed conditions. Although this process is based on the conventional routine process for the production of S30-extracts, our process is less labor intensive and reduces variability between extracts. © 2022.
