Introduction (download PDF) (Chinese

ECOSTM Competent
Cell is the first innovative product of Yeastern Biotech’s R&D team,
which strives to bring noble products that make research faster and
easier. ECOSTM is Yeastern’s registered trademark in USA, Japan, Canada, Korea, and
Taiwan. The
name speaks for the merits of this product - E. Coli One-Step transformation. The reverse of this
name is SOCE – SOC Eliminated.
|
|
|
|
ECOSTM
protocol allows users to finish the transformation within one step and to
skip the SOC recovery step. Therefore ECOSTM competent cells
are the fastest transforming cells worldwide. The traditional protocol
requires recovery step and takes 1 ~ 2 hours to finish, but ECOSTM
allows transformation to be finished within 1 minute and the procedures
are a lot simpler. Please check the ECOSTM protocol section.

ECOSTM Technology is Patented
|
|
Yeastern Biotech
Co., Ltd. owns the patent of ECOSTM technology (protocol)
exclusively in USA, UK, Taiwan, and France. (Patent
No. US 6,864,088; GB2383582; I 229696; FR 2832727, etc.) Under the
protection of this patent, Yeastern is the only company that has the right
to use the protocol with the claims that transformation can be finished
within one minute and SOC is not needed. If any one intends to sell
competent cells that use ECOSTM protocol or its similar version,
please contact our head office at Taiwan for
licensing.

ECOSTM Advantage
|
|
Compared to
traditional commercial competent cells
※ Revolutionary 1- or 6-minute transformation, instead
of 1 ~2 hours
※ Electronically monitored shipping process to check
temperature during shipping
※ Procedures are simplified
※ No addition of LB/SOC required
※ Several protocols to choose according to your needs
in efficiency and convenience
※ Strict QC process to check the efficiency of each
batch produced
※ Economic pricing for regular and high efficiency
cells
※ Ideal for bench users to automatize cloning projects
