Components


BL21(DE3) electrocompetent cells pUC 19 transformation control DNA recovery medium for expression


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


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.GenotypeF – ompT hsdSB (rB- mB-) gal dcm (DE3)
