\n
ECOS\u2122 competent cells is the fast transformation competent cells developed by Yeastern Biotech technology. 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\u2122 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.<\/div>\n
