General description

The BL21(DE3) pLysE Chemically Competent Cells produce T7 lysozyme to repress low-level transcription from the T7 promoter prior to IPTG induction, helping to stabilize inserts coding for deleterious products.
These cells have a higher level of repression by T7 lysozyme, offering the greatest control over expression of inserts.

Genotype

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

Features and Benefits

  • a transformation efficiency of >1 × 107 cfu/μg.
  • economical prices
  • offering superior value for everyday protein expression work.

Other Notes

  • BL21(DE3) pLysE chemically competent cells
  • pUC 19 transformation control DNA
  • recovery medium for expression
