FAQs
- Can I transform unmethylated DNA into dam–/dcm– competent E.coli (C2925)?
- Does New England Biolabs offer a methyltransferase free strain of Competent E.coli?
- How long should I incubate cells on ice after DNA has been added (NEB #C2925H and NEB #C2925I)?
- Is dam–/dcm– (NEB #C2925H/C2925I) resistant to kanamycin?
- Is the DNA yield lower using dam–/dcm– strain (C2925)?
- What are the solutions/recipes (C2925)?
- What are the strain properties (C2925)?
- What is the difference between NEB #C2925H and NEB #C2925I?
- What is the optimal heat shock time for this strain (NEB #C2925H and NEB #C2925I)?
- Which strain of Competent E.coli should I use for general cloning?
- Why were the colonies at different size after transformation of dam–/dcm– competent E.coli (C2925)?
- How should I calculate the transformation efficiency (C2925)?
- 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 #C2925H and NEB #C2925I)?
- 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?
