FAQs
- What are the solutions/recipes (C2566)?
- What are the strain properties (C2566)?
- Why are there no colonies or no growth in liquid culture (C2566)?
- Why is there no protein visible on gel or no activity (C2566)?
- Why is induced protein insoluble (C2566)?
- Can I store competent cells at -20°C instead of -80°C?
- What is the difference between NEB #C2566H and NEB #C2566I?
- What is the optimal heat shock time for this strain (NEB #C2566H and NEB #C2566I)?
- How long should I incubate cells on ice after DNA has been added (NEB #C2566H and NEB #C2566I)?
- Is T7 Express (NEB #C2566H and NEB #C2566I) compatible with auto-induction procedures?
- 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 #C2566H and NEB #C2566I)?
- Are NEB’s competent cells compatible with the “Mix & Go” protocol?
- What is the difference between T7 Express (NEB #C2566H/I) and BL21(DE3) (NEB #C2527H/I)?
- 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?
- Is T7 expression subject to catabolite repression in NEB T7 Express or SHuffle strains?
