Lucigens E. cloni EXPRESS BL21(DE3) Electrocompetent Cells are the first to offer high efficiency cloning and high level protein expression in the same cell. Cloning efficiencies are increased 25 1,000 fold relative to competitors preparations of BL21 cells (Figure 1), which is essential for construction of
