Abstract
|
|
|
|
In this report, we describe how reactions of cell-free protein synthesis can be successfully conducted using plasmids prepared with regenerated anion-exchange columns. When washed, stripped, and equilibrated with appropriated buffers, regenerated columns were able to be used repeatedly to prepare plasmids with consistent yield and purity. The regenerated columns exhibited comparable performance to a fresh column with respect to the efficiency of protein synthesis using the plasmids prepared from them. Overall, we expect that the presented results will contribute significantly to economizing the technology of cell-free protein synthesis as a practical method for protein production in preparative scales.
