FAQs
- Does New England Biolabs offer strains of Competent E.coli suited for protein expression?
- What are the solutions/recipes (C2529)?
- Why are there no colonies or no growth in liquid culture (C2529)?
- Why is the induced protein insoluble (C2529)?
- Why is there no protein visible by SDS-PAGE or no activity (C2529)?
- What are the strain properties (C2529)?
- 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 #C2529H)?
- 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?
- Is T7 expression subject to catabolite repression in BL21(DE3) and derivative strains?
- What expression plasmids can be used with NiCo21(DE3)?
