Notes

  • If you are in a hurry and your selection marker is ampicillin and you're sure to have enough plasmid (e.g. not after difficult clonings), you can go ahead and plate immediately because ampicillin takes a while to be pumped into cells at a high enough concentration to have an effect. This is called 5-minute transformation by New England Biolabs and if you follow the link you'll get a nice complete protocol for it (10% efficiency compared to full protocol)
  • The Endy Lab is trying to use a standard positive control to better compare (and hopefully improve) the transformation efficiencies in the lab, you can check it out here.
