• Screening for the 11 miniprepped DNA samples for B1: digestion S-P for all.

• Gel results:
  • Samples 1, 4, 10, 11, 14, 19 and 20 showed an extra band for the non ligated plasmid;
  • Samples 2, 9, 13 and 18 were pure! we decided to keep B1-13 (lane 8) to perform future ligations.

• NOTE: we had a pure sample for B1 (i.e. B1-13)and three almost-pure sample for B2. Anyway, we decided to perform ligation reactions for these samples and the extra band of B2 will be eliminated during gel cut/purification. WE DECIDED TO KEEP B2-5. Next weeks we will think about purifying B2-5 itself.

• We transformed 20 pg of B1-13 purified DNA (stored at -20°C) in TOP10 in order to prepare a glycerol stock for this construct. We incubated the plate at 37°C overnight.

Preparation of experiment with Tecan F200

• We infected 5 ml of LB + Amp with 10 ul of A14pg, A8pg and A9pg glycerol stocks.

• We also infected 5 ml of LB + Amp with a single colony taken from B0030 native plate (stored at +4°C).

• We incubated the inocula at 37°C, 220 rpm overnight.
