TSS Solution - 1-step Competent Cell Preparation

Features & Benefits

• Single-step preparation of competent cells
• Just resuspend in TSS and you're ready to transform
• Store prepared cells at -70°C with little or no loss in efficiency
• No heat-shock needed
• Transformation efficiencies of 10^7-10^8/µg DNA for DH5-alpha

Description

Transformation & Storage Solution (TSS), developed at the U.S. National Institute of Health, enables researchers to prepare competent E. coli in a single step and to transform the cells without heat-shock.

TSS is faster and easier than other methods of producing competent cells, such as the traditional CaCl2 method or other high-competency protocols.
