Summary
Automatic Translation

Presented here is a protocol for the preparation and buffer calibration of cell extracts from exonuclease V knockout strains of Escherichia coli BL21 Rosetta2 (ΔrecBCD and ΔrecB). This is a fast, easy, and direct approach for expression in cell-free protein synthesis systems using linear DNA templates.
