-
Three strains of bacteria containing MerT and MerP genes, including M3 JM109 pSUTP. pG.pmt (AmpR + KanR), M4 JM109 pG.pmt (AmpR) and M18 JM109 pSUT (AmpR) , were culture overnight at 370C on shaker.

'''15/09/09 - Repeat Transformation of BBaI716101'''<br/>
+
-
The overnight transformation from 14/09/09 was unsuccessful as no growth was observed on plates. It is probable that the cell death plasmid component (Part BBa_P1010) is functioning normally as it was believed that this component was 'faulty'. The same protocol as on 14/09/09 was used for the transformation with an extra positive control for comparison. A well characterised plasmid PUC18 (ampicillin resistance) was used as the positive control.
+
-
 
+
-
'''14/09/09 - Transformation of Plate 1, Well C'''<br/>
+
-
PLasmid BBa_I716101 with Part BBa_P1010 was transformed into XL-10 Gold Ultracompetent cells via heat shock and left in ampicillin plates at 37C overnight. DNA from plate 1, well C was stored in the Green iGEM box ('Fiona').<br/>

+
-
* 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.<br/>

+
-
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.<br/>
+

-
'''25/08/09  - In-gel Extraction and Overnight Digests'''<br/>

PXCK-K and PXCK-EL plasmids were transformed into electrocompetent E. coli and left overnight at 37C in ampicillin plates (PXCK-K) or chloramphenicol plates (PXCK-EL).<br/>

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!

Miniprep of bacterial cultures. For procedure click [https://2009.igem.org/Team:UQ-Australia/Notebook/Miniprep_procedure HERE]. Plasmids were stored in -20'C freezer (FIONA).

-
'''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.

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.
