产品介绍:

产品说明

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)

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

组分

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