Continuation of making competent cells

Step 2-12 in "800 ml of competent cells"

1 L instead of 800 ml -> 25 st 50 ml Falcon Tubes with 40 ml, 1 st with 15-20 ml

10) 16/23 = 0,69 ml

3) Abs:

Only one bottle

  • 0,029 9:25
  • 0,053 ~1h5min
  • 0,188 ~1h5min
  • 0,316 ~30min

Both bottles

  • 0,519 ~30min
  • 0,503
  • 0,578 ~7min
  • 0,566
  • 0,598 ~5min = 13:05
  • 0,600

12) ~160 epps, 100 µl in each.

They were then all put in the freezer, in two cardboard boxes (no metal blocks used)
