WebThe pellet from cell harvest is resuspended in a suitable buffer for cell disruption (e.g., PBS). DNase is added to reduce viscosity. It is useful to add a protease inhibitor cocktail to reduce possible protein degradation. A selection of commonly used techniques for cell disruption are summarized in Table 1.2. WebHere, we combine programmed cellular autolysis with a freeze-thaw or freeze-dry cycle to create a practical, reproducible, and a labor- and cost-effective approach for rapid production of bacterial lysates for cell-free gene expression. Using this method, ro-bust and highly active bacterial cell lysates can be produced without specialized ...
