BL21(DE3) Electrocompetent Cells
基本信息
| NACRES | NA.85 |
| General description【一般描述】 | 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【特点和优势】 | 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 |
