- What is the difference between NEB #C2992H and NEB #C2992I?
- What is the optimal heat shock time for this strain (NEB #C2992H and NEB #C2992I)?
- Which strain of Competent E.coli should I use for general cloning?
- Can I store competent cells at -20°C instead of -80°C?
- Which kind of transformation tubes should be used?
