说明

一般說明

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)

特點和優勢

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

成分

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