Subject: [ccp4bb] Protein expression in Minimal media (M9)
Hello everybody,
Sorry for an offtopic question. I am trying to express a protein in M9
minimal media
Manish,
I also had a similar problem getting cells (C41 (DE3) in my case) to grow
in minimal media. To get around this problem, I took cells from an agar
plate and grew them in a small volume (5 mL) of the minimal media. Once
that culture got thick, I then inoculated 200 mL of minimal media with
Are you adding vitamins to your M9 minimal? RosettaBlue is thiamin
requiring and can not grow in the absence of thiamin. The thiamin
requirement is so low that you can often get slow growth to a low OD
based on residual thiamin in the cells, but you will not get robust
growth.
Also,
Manish,
Assuming that you need the minimal medium for Se, have you tried the
regular heavy atom derivatives? You already have diffracting crystals...
M9 medium can be slightly difficult. However, no one says that you *have*
to use minimal medium such as M9 (again, assuming that you're doing
