Our open day preparation did not go as planned. Most of our transformations were unsuccessful, we believe this was because SOC was added after the heat shock. As disappointing as this was, there was one little piece of good news.
A single colony of Top 10 E.coli containing GFP insert was identified on a plate of LB agar media.
LB agar and nutrient agar plates were struck using this colony. The colony was also used to inoculate 5mL of nutrient broth. Plates and stock were then incubated at 37°C overnight. Both of the streaked plates and the broth showed significant growth of E.coli colonies which could fluoresce when exposed to UV light.
Unfortunately, Qantas declined to sponsor the effort of getting our team to Hong Kong. This was soon forgotten when the Macquarie University School of Medicine, Agilent and the Defence Science Institute (thanks Yagiz) both agreed to sponsor our team. Hong Kong here we come.

Matt looked at the transformed cells we cultured the previous day (04/09/12). Two small colonies of the transformed Deinococcus bacteriophytochome without the T7 promoter were grown on kanamycin. The positive control was successful, so we could infer that the reactions were proceeding as expected. The positive control was also cultured on XGal and incubated overnight.
The Deinococcus was cultured in 2 tubes of LB broth (2 mL) containing kanamycin. The transformations performed on the previous day were done again with a slightly different method. We choose to redo the transformations as the efficiency was relatively low. The transformations were re-innoculated onto fresh plates and incubated over night.

We continued on from the Gibson assembly and transformations we performed on the 04/06/12. Daniel did a plasmid prep using a QIAprep Spin Miniprep Kit by Qiagen, for two colonies from Deinococcus.

Plasmid Preparation was continued from Thursday, by Daniel and Harry, using the QIAprep Spin Miniprep Kit by Qiagen. A total of 7 colonies cultures were used used as the remaining did not grow. Successful cultures included 1C (1-6) and 3K (3). The DNA concentration was then determined for each sample by NanoDrop, with EB buffer from the Miniprep Kit used as a blank.
NanoDrop Results
Purified Plasmid Samples then underwent sequencing at the Macquarie University Sequencing Facility. Each sample contained 10 uL Plasmid (>50ng/ul)and 1 uL of BB forward and reverse sequencing primers.
