July, 1st

19° Bio-Lab - I7-3,4 and 5 and I8-3, 4 and 5 were prepared for TECAN test.
Of the plates incubated yesterday, a colony was picked and grown in 1ml LB (+ antibiotic) for 6 hours at 37°C 220 rpm. Other parts were received from Anderson Lab.

July, 2nd

20° Bio-Lab - TECAN test provided encouraging results, showing that I7-3, I7-5, I8-4 and I8-5 produced GFP.
Other culture (I7-1, I7-2, I7-4, I8-1, I8-2, I8-3) did not produce GFP, so they were thrown away. A furhter screening were performed on I7-3, I7-5, I8-4, I8-5 and this time all the clones are OK . Inoculum of <partinfo>BBa_J72007</partinfo> and <partinfo>BBa_J72013</partinfo> from LB agar plates.A glycerol stock was prepared for each culture.

to check transformation efficiency.

July, 14th

29° Bio-Lab - PBHR68 plate showed colonies!!transformation of ligation of yesterday. Screening of <partinfo>BBa_J72007</partinfo> (CRIM), <partinfo>BBa_J72008</partinfo> (helper), pAH123 (helper) ans pCP20 (helper).

July, 15th

30° Bio-Lab -Agar plates after transformation were checked(2 colonies were picked from every plate). MiniPrep was performed for:

  • PBHR68 (BioPlastic operon) -> 272 ng/ul
  • BBa_J72007(CRIM plasmid) -> 41 ng/ul (not clean spectrum at 230nm)
  • BBa_J72013(CRIM plasmid) -> 16 ng/ul
July, 16th

31° Bio-Lab - MiniPrep was performed on 23 falcon tubes containing I11 -> I19 and I7/8/10-4C5 ligations. We decided to performe a TECAN test on our parts, in order to see if RFP was correctly excided from BBa_J231xx vector, since length of RFP and of our insert (RBS-luxI-tt) were similar.

July, 19th

32° Bio-Lab - TECAN test showed that no RFP was produced from our parts.I14-1, I16-1, I17-1, I18-1, I19-1, I74c5-2, I84c5-2 and I12-2 were sequenced. Trasformation of RING into:

  • BW25141 (pir+)
  • BW25142 (pir116)
  • BW23474 (pir116)
  • DH5alpha
  • MG1655
July, 20th

33° Bio-Lab - Agar plates after transformation were checked (Single colonies were picked from plates). MiniPrep was performed on I10-1, I12-2, I3-1, I14-1, I17-1 and <partinfo>BBa_J23110</partinfo>. Following ligations were performed: I15_new, I14_4C5, I16_4C5, I17_4C5, I18_4C5 and I19_4C5.
