CloneJET™ PCR Cloning Kit with DH10B Competent Cells, 40 Reactions - FAQs

How can I obtain the highest possible transformation efficiency with Thermo Scientific DH5α and DH10B competent cells?

To achieve the highest possible transformation efficiency with Thermo Scientific DH5α (Cat. No. EC0112) and DH10B (Cat. No. EC0113) competent cells, please follow the transformation protocol provided with the product and pay attention to the following details:

- Make sure to use wet well-pressed ice to maximize cold surface volume in all the transformation steps.
- Perform the steps quickly and accurately.
- Use chilled microcentrifuge tubes and bury the whole tube up to the cap in the wet ice.
- Do not exceed the recommended heat shock time and transfer the tube with cells back to the wet ice immediately.
