ECOS™ Sonic™ Competent Cells [BL21(DE3) Derived]

ECOS™ competent cells is the fast transformation competent cells. Without additional gene modification, the process takes less than 6 minutes to yield the high efficiency without the need of SOC recovery (with ampicillin).
ECOS™ Sonic competent cells is the derivative of BL21(DE3) strain.
It inherits the protein expression and fast-growing feature from its parent strain. The further deletion of endA and recA improve the quality of plasmid DNA and enable the plasmid extraction in 3-6 hours growing.

Features and Advantages
• High efficiency
• Hiyield and rapid plasmid production (only 4~6 hr needed)
• Direct plasmid extraction
