Opis

General description

The 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 other preparations of BL21 cells, which is essential for construction of complex expression libraries.

Genotype

F – ompT hsdSB (rB- mB-) gal dcm (DE3)

Features and Benefits

The unprecedented transformation efficiency of the BL21(DE3) Electrocompetent Cells (> 5 × 10⁹ cfu/μg) eliminates the need for plasmid transfer from the cloning strain to the expression strain, saving days of work in a typical cloning and expression experiment

Other Notes

• BL21(DE3) electrocompetent cells
