Day 27 28/07/15
We made new Chloramphenicol broth and Ampicillin broth. We then used the Amp broth to resuspend Top10 cells with pVS105. We then resuspended VS45 with pVS72 in combined Chloramphenicol and Ampicillin broth. We incubated these cultures overnight at 37ºC. For the remainder of the day, we focused on dry lab tasks.
Day 28 29/07/15
In the morning, we miniprepped the Top 10 cells containing pVS105. This will be our negative control plasmid. Following this, we diluted our culture of VS45 with pVS72 to an OD600 of 0.1 in 3ml of LB. Once the correct OD600 had been achieved, we spot plated 5μl of the culture onto inducing plates (containing Arabinose and IPTG), non-inducing plates and Congo red plates (both inducing and non-inducing).
Day 29 30/07/15

Day 31 03/08/15
We focused on dry lab tasks such as planning the questions to ask MP's and developing the questionnaire.
Day 32 04/08/15
Our transformed pVS105 in VS45 weekend cultures were spotted onto Chl + Amp plates (both inducing and non-inducing) and Congo Red. These plates were incubated overnight at 37ºC.
Day 33 05/08/15

Day 34 06/08/15
We set up overnight cultures of pVS105 in VS45 and pVS72 in VS45.
Day 35 07/08/15
As the colonies did not grow overnight, we set up more colonies in the morning, with the OD600 being checked in the evening. The transformation of pVS105 and pVS72 into VS45 was then repeated. The transformations were then plated out and incubated at 37ºC.
Day 36 10/08/15
Our miniprepped plasmids (pSBIC3, pSBIA3, pVS105 and pVS72) were digested and run on an agarose gel. VS45 colonies containing pVS105 and pVS72 were resuspended in liquid LB and cultured overnight at 37ºC.
Day 37 11/08/15
First we checked the OD of the overnight cultures. We transformed pSBIA3 and pSBIC3 into Top10 cells. We made a glycerol stock solution of pVS105 and pVS72 to store it for future use. We spot plated the pVS72 and pVS105 separately onto plates for imaging. We then miniprepped pVS72 and pVS105 from the overnight cultures.
Day 38 12/08/15
First, we re-transformed pSBIA3 into Top10 cells. We then did PCR of pSBIC3 and pVS72.
Day 39 13/08/15
As PCR did not work properly the day before, we repeated the procedure. We also scanned the streaked Congo Red plates.
Day 40 14/08/15
We purified the PCR product, then digested it. We then measured the concentrations of our stock of pSBIA3 and pSBIC3.
Day 41 17/08/15
We ligated pSBIC3 and pVS72, then transformed it into competent Top10 cells. We then plated it onto Chloramphenicol plates. We used an agarose gel to test if the digest from the day before had worked successfully and also to find out if the PCR had worked. We also prepared our samples for imaging.
Day 42 18/08/15
We set up overnight cultures of the transformed ligations.
Day 43 19/08/15
We miniprepped the overnight cultures of the ligated pSBIC3 and pVS72 that were cultured overnight. Following the miniprep, we digested the plasmids. Simultaneous to the digest, we transformed 1µl of the plasmid into VS45 competent cells.
Day 44 20/08/15
We ran an agarose gel of digested plasmids from the night before. Overnight cultures of ligations of pSBIC3 and pVS72 were also set up.
Day 45 21/08/15
We miniprepped the overnight cultures. Following the miniprep, we ligated pSBIC3 and pVS72 as the previous ligations did not work. Alongside the ligations, some of the team members used Gibson assembly to fuse fragments containing CsgAss and Sup35NM to pSBIC3. The Gibson assembly products were then transformed into competent cells and incubated at 22ºC over the weekend.
Day 46 24/08/15
We carried out Gibson assembly of fragments containing CsgAss, Sup35NM and Cytochrome b562, followed by transformation into competent cells. The ligations from the day before were digested and run on a gel. We set up overnight cultures of the Gibson assembly product from 21/08/15.
Day 47 25/08/15
We carried out PCR of fragments and set up overnight cultures of the Gibson assembled fragments that grew overnight. We then miniprepped and set up a digest of the Gibson Assembled fragments containing CsgAss and Sup35NM from the overnight cultures. From the digest, an agarose gel was run.
