Competent Cells

The fastest transforming cells worldwide-

1 minute transformation

With “ECOS™” standing for “EColi One-Step”, and its reverse “SOCE” standing for “SOC Eliminated”,  the name itself speaks for the advantages.

minute, 1 step high-efficiency transformation and no SOC recovery step required, truly a design to save your time.
