Designing the protein expression vector. The two characteristics that we are looking for are:
+
<div id=" .2F28_June_2010">
-
*Strong promoter
+
===28 June===
-
*Inducible
+
-
In order to achieve these two aims, we will use the biobrick '''BBa_R0010''' which is an (lac) inducible promoter and incorporate a T7 promoter to it. This process involves the removal of the -35 and -10 promoter sites and the incorporation of the T7 promoter sequence.
+
Did OH&S training and PC2 training
-
By mutagenesis we aim to turn the promoter elements into restriction sites (which are not found in the plamsid), thus being able to remove the promoter section and then introducing the T7 promoter sequence by ligation.

-
We found the ''T.aquaticus'' DNA polymerase sequence from the NCBI website. From this, we designed primers that contained restriction site "sticky ends" on the 5' and 3'. The restriction sites that are going to be used for introducing Taq into the vector are XbaI (5') and SpeI (3').

PCR of Taq
 +
 
 +
Taq with a DNA concentration of 40ng/µL was diluted to 1µM by addition of 24µL of MilliQ water to 1µL of the Taq plasmid. Primers were diluted to 100µM by adding 354µL to the forward primer with a concentration of 35.4 nmol and 405µL to the reverser primer with a concentration of 40.5nmol. The primers were further diluted to 0.2µM by adding 10µL of the primer to 490µL of milliQ water. The PCR reaction was then made by adding 25µL of Master Mix, 2.5µL of each primer, 5µL of Rnase free water and 15µL of 0.2µM Taq Plasmid.

Got it!
 +
The problem was the plasmid backbone. It was thought that it was pSB1A3, but in fact it was pSB1AK3. Kanamycin has a ClaI site.
 +
 
 +
A restriction digest was performed using EcoRI and PstI. The RFP plasmid was also digested with EcoRI and PstI. A ligation reaction was performed in order for the promoter part to switch backbones (from pSB1AK3 to pSB1C3).
 +
RFP is also a form of control mechanism to see if the plasmid has the correct insert. Red colonies have RFP, while White colonies have our insert. Overnight ligation at 16 degrees.

PCR of Taq

Taq with a DNA concentration of 40ng/µL was diluted to 1µM by addition of 24µL of MilliQ water to 1µL of the Taq plasmid. Primers were diluted to 100µM by adding 354µL to the forward primer with a concentration of 35.4 nmol and 405µL to the reverser primer with a concentration of 40.5nmol. The primers were further diluted to 0.2µM by adding 10µL of the primer to 490µL of milliQ water. The PCR reaction was then made by adding 25µL of Master Mix, 2.5µL of each primer, 5µL of Rnase free water and 15µL of 0.2µM Taq Plasmid.

18 August

called few companies seeking sponsorship enquired for booking flights and accomadation

19 August

Working on comparing TAQ wild structure to the TAQ Mutated structure to see that there are no major differences, which will mean that TAQ is inactive but will retain it's thermostability at high temperatures.

Wrote an email to ABC TV, wanting to know if they will do piece on our project for there The New Inventors Program.

Waiting for results from I-Tasser on the mutated TAQ sequence. Went into the lab and made SOC media and LB- agar plates

20 August

2 µl of the mutagenesis product into 100 µl of competent cells Plate 50 µl, 100 µl and 150 µl samples.

17 September

- finalized project abstract

19 September

- Sent off project abstract to HQ

20 September

Two colonies were picked from the plates and were grown in 5mL of Media

21 September

A miniprep was performed on 1.5ul of the overnight culture. 10ng/ul DNA were obtained from both samples with a O.D higher than 1.85. These samples were then used to perform a restriction digest using EcoR1 H.F and AflII. The restriction digest was done according to the iGEM protocols [http://ginkgobioworks.com/support/BioBrick_Assembly_Manual.pdf CLICK HERE].

Results The restriction digest did not work. We expected a band at 160bp and one at ~3000bp

22 September

Results The restriction worked. Gel Image below

23 September

Second mutagenesis. This involves changing the -10 promoter region into a ClaI restriction site. AflII (11) miniprep sample was used as template

Click Here for Mutagenesis Protocol

After the Dpn1 digest, 2ul of product was transformed into E.coli Xl1 blue cells.

24 September

Colonies grew on the plate. This was stores in the fridge (4 degrees) until Monday for colonies to be picked.

27 September

Two colonies were picked from the plate and grown overnight at 37 degrees in the shaking incubator.

28 September

Preparation of plasmid DNA using Invitrogen Miniprep Kit. Obtained ---ng/ul (260/280 = ---)

Restriction digest using EcoRI and ClaI, then gel electrophoresis. Strange gel picture. Two bands of similar size ~ 1.3 kb and 1.6 kb appear on the gel.

29 September

Two more colonies (different) were picked and grown overnight at 37 degrees.

Transformation of RFP in Ampicillin, Kanamycin and Chloroamphenicol backbones. They will act as spare backbones.

30 September

A second preparation of plasmid DNA using Invitrogen Miniprep Kit. Obtained ---ng/ul (260/280 = ---)

Restriction digest using EcoRI and ClaI, then gel electrophoresis. Strange gel picture again. Two bands of similar size ~ 1.3 kb and 1.6 kb appear on the gel. There is a problem with the backbone or the miniprep. Must investigate.

4 October

Got it! The problem was the plasmid backbone. It was thought that it was pSB1A3, but in fact it was pSB1AK3. Kanamycin has a ClaI site.

A restriction digest was performed using EcoRI and PstI. The RFP plasmid was also digested with EcoRI and PstI. A ligation reaction was performed in order for the promoter part to switch backbones (from pSB1AK3 to pSB1C3). RFP is also a form of control mechanism to see if the plasmid has the correct insert. Red colonies have RFP, while White colonies have our insert. Overnight ligation at 16 degrees.

5 October

The ligation product was transformed (5ul) into E.coli XL1 Blue competent cells.

6 October

Colonies grew. Two white colonies were picked and grown overnight in the shaking incubator at 37 degrees.

7 October

Slow growth on Chloroamphenicol. Cultures were left on the shaking incubator for an extra night.

8 October

Miniprep of the colonies. One successfully grew, while the other did not. Miniprep results gave a concentration of 114ng/ul with a 260/280 of 1.98. Woohoo.

Double digest (diagnostic) with NcoI and AflII/ClaI --> to check the success of mutagenesis. Gel result gave strange band pattern.

11 October

Single restriction digest (AflII/ClaI) verified the size of the plasmid. Will re-do double digest tomorrow.
