02/09/09 - Running Gel for Standard 23
2 gels were set up: - A--->1%, 140mL gel.Undigested and digested controls. Undigested/digested plasmid BBa_J63010 (Sample A, B and C) - B--->1%, 80mL gel. Undigested and Digested BBa_J63010 (Sample D,E)

01/09/09 - Agarose Gel and Nanodrop

• Miniprepped BBa_J63010 plasmids ran on 1% Agarose gel (TAE buffer, pH8.5) at 200V, 70mA for 1hour. Post-stain: Ethidium Bromide.
  
• Miniprepped BBa_J63010 plasmids (tubes A to E) analysed on nanodrop. (Data printout in IGEM_Mercury notebook)
  
• New space created for BBa_J63010 tubes A to E: in "Fiona" freezer, UQ-Australia IGEM Team's Green box.
  
• In the afternoon, digests of samples BBa_J63010 A-E (Standard 23) were run with EcoRI, AgeI, SpeI and PstI enzymes. Unfortunately NgoMIV enzymes were not in stock in the freezer so this digest could not be performed.
• The Standard 21 plasmid BBa_I716101 was again digested with PstI. All samples were left in the 37 degrees water bath overnight.
  

28/08/09 - DNA miniprep
Mini prep DNA extractions performed for BBa_J63010 plasmid selected yesterday and incubated overnight.
Tubes stored in "Fiona" freezer, UQ-Australia IGEM Team's orange box.

EDIT (01/09/09): these tubes now in IGEM
Green Box ("Fiona" freezer, bottom shelf).

27/08/09 - Colony Picking
5 colonies were picked and grown in ?mL of LB Broth and were left in the 37C incubator overnight. Samples were labelled 'BBa_J63010 A,B,C,D,E'

26/08/09 - Transformation of Plasmid BBa_J63010 with part BBa_J04450
BBa_J04450 was found in plate 1, well C. Colonies were grown overnight and will be picked and grown tomorrow.

--->Digest Gel of BBa_I716101 with pGfa2cLac2 control
A 1% agarose gel was run with 1kb ladder and samples with EcoRI, XhoI, BglII and BamHI restriction enzymes. The gel visualisation (image here) indicates that only EcoRI was able to slice the plasmid; it is possible that the other restriction sites are not on the plasmid.

25/08/09 - In-gel Extraction and Overnight Digests
20 chloroamphenicol plates were prepared with LB agar. BBa_I716101 and control plasmid pGfa2cLac2 were each digested with EcoRI, XhoI, BglII and BamHI enzymes (total of 8 samples). Digests have been left to run overnight in the 37C waterbath.

24/07/09 - DNA extraction and electrophoresis
Mini prep DNA extractions performed for MS427-pBAD, MS427-pKKJ143 cultures incubated overnight.
--> run on ethidium bromide gel to confirm DNA production.

Strain: MS427 

Plasmid: pBAD (empty plasmid -AG43) 

- 2mL LB broth

20/08/09 - Plasmid Digestion

19/08/09 - Miniprepping and Running PCR Gel + Nanodrop

18/08/09 - PCR Preparation and Picking Cultures

24/07/09 - Extraction of DNA from E.coli M5427

17/07/09 - MG1655 Stock Preparation
MG1655 E. coli grown on pure LB stock. No growth was observed using LB + ampicillin medium.
Pelleted and resuspended in 50:50 glycerol:LB medium and stored at -80 degrees C.

Bioprecipitation Project

08/09/09 Our Primers have arrived today, this means we can start to put our four genes into the standard plasmids!

02/09/09 For the last couple of weeks we have been trying to design primers in order to put them into the iGEM standard plasmids. Since restriction sites are against us, we are using mutagenesis in order to bypass this problem. Primers were ordered TODAY!

19/08/09 Miniprep of bacterial cultures. For procedure click HERE. Plasmids were stored in -20'C freezer (FIONA).

18/08/09 Colonies were picked from transformed bacteria. Protocol can be found by clicking HERE.

14/08/09
Results from transformation 2

• pxCK-EJ = 1 colony
• pxCK-ES = 3 colonies
• pxCK-EL = 27*4 colonies
• pxCK-K = 53*4 colonies

Plates were sealed with parafilm and stored in the -4 fridge.

13/08/09 A second transformation was performed on the four plasmids. Procedure slightly changed, click HERE to see it.

11/08/09 No results were given from the transformation. Transformation will have to be repeated.

10/08/09 Transformation of our 4 plasmids took place. They were transformed into TOP10 bacteria. A colony check will be preformed tomorrow morning.

To see protocol, click HERE

7/08/09 Vectors were examined and we are planning for the best cloning strategy for the standard plasmids.

6/08/09 Plasmid solutions were left overnight and in the morning checked again with Nanodrop. No DNA was measured. Samples were put in the waterbath at 37 degrees and left for a couple of hours. If Nanodrop does not work after the waterbath we will still do transformation since we only need few plasmids for the transformation to work. Nanodrop may not have been able to quantify such a small concentration of plasmids.

LB media was poured on petri dishes and plasmid DNA was checked again using Nanodrop.

• pXCK-EL = 10.55 ng/uL
• pXCK-ES = 8.43 ng/uL
• pXCK-K = 11.73 ng/uL
• pXCK-E/J = 2.66 ng/uL

Plasmids were stored and transformation will be done on Monday.

5/08/09

Plasmids have arrived!

• pXCK-E/J
• pXCK-K
• pXCK-EL
• pXCK-ES

We have put them into 150 mL of TE buffer and left overnight for the paper to dissolve and later extract the plasmid from the solution.

A Nanodrop was used to see if the DNA was coming out of the paper. No DNA was detected, thus samples were left overnight.
