2X TSS Bacterial Transformation Kit for Fast Preparation of Competent E.coli Cells

Transformation and Storage Solution (TSS) is used for the preparation of competent E. coli cells in a single step and to transform the cells without heat-shock. Amid Biosciences' TSS is optimized version of solution described initially by Chung et al. (1) and contains DMSO, PEG, Mg²⁺ salts, along with proprietary additives. This solution allows rapid preparation of the competent cells with typical transformation efficiencies that range from 10⁵ to 10⁷ cfu/µg of DNA, however, the transformation efficiencies up to 10⁸ can be obtained for some E. coli strains.

For applications that require high efficiencies (e.g. library preparations, transformation of ligation reactions), Amid Biosciences’ selection of ready-to-use Chemically Competent or Electrocompetent Cells would be a good choice.

Benefits

• Fast preparation of competent cells.
• Suitable for various E. coli strains (DH5a, HB101, JM109, XL1-Blue, and etc.)
• Transformation cells without heat-shock.
