Week 1: from 07/20/09 to 07/24/09

Trasfomation of PSB1K3, PSB3K3, PSB1A2, PSB4A3(2007). Only the last one seems to work. We also use PSB1A2.

Trasformation and Amplification of A, B, C:

A) PSB3K3(LMC) + 1429 + RBS + LACI
B) PSB1A2(HC) + 2547 + Ox + RBS + GFP + T
C) PSB3K3(LMC) + 1429 + RBS + GFP + T

Working (using DH5alfa) on:

A + B ---> Evaluation GFP fluorescence imaging comparing with the rRBS one
B ---> Evaluation GFP fluorescence imaging
C ---> Evaluation GFP fluorescence imaging
B+C ---> Evaluation ΣGFP fluorescence imaging

Up

Week 2: from 07/27/09 to 07/31/09

Sequences suspension to have 100 μM conc. (EP digestion and trasformation in a HCN plasmid with AMP)

DNA sequences	Plasmid
H2O mQ == 4.5 μM	H2O mQ == 19.5 μM
Sequence == 20 μM	DNA (miniprep) == 5 μM
Buffer == 3 μM	Buffer == 3 μM
BSA == 0.5 μM	BSA == 0.5 μM
EcoRI enzyme == 1 μM	EcoRI enzyme == 1 μM
Pst1 enzyme == 1 μM	Pst1 enzyme == 1 μM
TOT: 30 μM	TOT: 30 μM

Gel Run:

1.CIS
2.TRANS 4
3.MARKER
4.TRANS 7
5.PSB1A2

CIS, TRANS 4, MARKER, TRANS 7, PSB1A2

Up

Week 3: from 08/3/09 to 08/7/09

Amplification of CIS, TRANS 4 and TRANS 7 using PSB1A2. Inoculation and digestion.
Unexpeted results from the gel run in all three sequences (3000, 2200, 1000 bp instead of 2100, 2000, 100 bp):

Digestion of CIS, TRANS 4, TRANS 7 with unexpected 1000 bp insert

Done the ligation again whit the same bad results.
Done some test fluorescence measurements using GFP in plasmids with different copy number.

Up

Week 4: from 08/10/09 to 08/14/09

HOLIDAY!!!

Up

Week 5: from 08/17/09 to 08/21/09

Done again the amplifications of CIS, TRANS 4 and TRANS 7 using PSB1A2 to undestand which is the problem we have had during the third week. Achieved the same wrong results.
We decided to sequence the 1000 bp strand to understand what it really is. We sent our material to the Bmr-genomics in Padova for the dna sequencing.

Up

Week 6: from 08/24/09 to 08/28/09

Bad news for our team:

Re-Annealing of our sequences and after have done the PRC-Colony we discovered that the colonies were green. Probably due to a GFP contamination. The DNA sequencing coming from Padova confirmed our theory: in the 1000 bp strand there was the presence of GFP protein and no sign of our CIS or Trans sequences.

Up

Week 7: from 08/31/09 to 08/4/09

Done some experiments (trasformation and digestion with the same plasmid, PSB1A2, using different concentration of annealed) to confirm the Gfp contamination. All the gel runs have a 1000 bp strand.
Investigation to discover where is the contamination.
Starting use a new plasmid: PSB4A3. Trasfomation and digestion with the CIS sequence. From the gel run came out a 400 bp insert that could be correct (CIS+Primer=100bp+270bp=370bp):

PCR Colony: CIS using PSB4A3 in the first well, CIS using PSB3K3 in the others.

The same attempt with TRANS 4 and TRANS 7 didn't give us any concrete resulst.
