FAQs
- Which competent cell strains are compatible with Gateway® Cloning?
- Does plasmid size affect colony size (C2984)?
- How long can I purify plasmid after the inoculation from a single colony using NEB Turbo competent E.coli (C2984)?
- How long should I incubate cells on ice after DNA has been added (NEB #C2984H and NEB #C2984I)?
- What are the strain properties (C2984)?
- What does the growth curve of NEB Turbo cells look like compared to DH5α?
- What is the difference between NEB #C2984H and NEB #C2984I?
- What is the optimal heat shock time for this strain (NEB #C2984H and NEB #C2984I)?
- Which strain of Competent E.coli should I use for general cloning?
- How should I calculate the transformation efficiency (C2984)?
- What are the solutions/recipes (C2984)?
- Can I store competent cells at -20°C instead of -80°C?
- Which kind of transformation tubes should be used?
- What volume of DNA can be added into competent cells?
- What is the shelf life for this strain (NEB #C2984H and NEB #C2984I)?
- Are NEB’s competent cells compatible with the “Mix & Go” protocol?
- How should I store SOC Outgrowth Medium? The SOC I received with my competent cells recommends storage at either room temperature or 4°C, however, when I purchase it as a stand alone product, it recommends storing it at 4°C. Which is better?
- How should fragments be prepared for assembly using NEBuilder HiFi?
- Are NEB Turbo Competent E. coli (High Efficiency) or NEB Turbo Electrocompetent E. coli recommended for cloning repetitive or unstable DNA?
