These questions are "open" to me, not necessarily the scientific community. If you have insights or can point me toward references relevant to them, please do!

Open Questions

  • What causes an overloaded colony PCR reaction to fail?
  • How does plasmid copy number get affected by oxygen availability? Cellular media? I have noticed that LB often gives me orders of magnitude lower plasmid yields and that growing cultures with liquid:air volumes higher than 1:5 is not good.
  • How do I decide whether to gel purify after digestions (before ligations)? The BioBrick/Ginkgo manual doesn't instruct you to. Besty always does.
