• We inoculated:
  • 10 colonies from B5new2 plate in 4 ml of LB + Kan for screening;
  • B8-5 (8 ul from glycerol stock) in 4 ml of LB + Kan (for purification process);

• We sent A15-2 purified DNA (stored at -20°C) to BMR Genomics for sequencing.

September, 1st

• We received sequencing results for:
  • A16-4: sequence ok!
  • A14-3: sequence had a deletion in C0012, as we expected because of A11-2 sequencing results, previously received;
  • B8-5: sequence wrong in VF2 and good in VR;
  • A17: chromatogram was good, but ligation failed (R0011 was not in the insert).

• COMMENTS after sequencing results:
  • now we have a new aTc sensor (A16) to test together with A9;
  • B8 has to be repeated or purified, we will try both the approaches;
  • A14 has to be repeated using A11-3, which has a consistent sequencing result;
  • A17 is going to be ligated today (this time using gel extraction).

• Glycerol stocks for the 10 B5new2 grown cultures.

• Miniprep for B5new2 (10 samples) and for B8-5.

• Digestion for:
  • B5new2 (10 samples) for screening (E-P cut);
  • B8-5 for purification from gel (E-P cut);
  • R0011 (stored at -20°C) for A17new ligation (S-P cut)
  • E0240 (stored at -20°C) for A17new ligation (X-P cut)

• Medium-size gel for B5new2(E-P); small-size gel for B8-5(E-P), R0011(S-P) and E0240(X-P).

• Medium gel results: B5new2 clones all showed the correct length for ligated plasmid!

• Small gel results: R0011(S-P) and E0240(X-P) were cut and purified through gel-extraction, while B8-5 could not be cut because the bands were not correct: maybe the heaviest band noticed
