Verification Digest of J13002-LuxOD47E-B0015
Lanes 2, 4 and 6 are colonies 1, 3 and 5 uncut. Lane 7 is B0015-J13002-LuxOD47E. The bands are the expected sizes whixh is good. We will send colony 3 down for sequecing tomorrow as the band for the construct looks the higest, so it has the greatest chance of having the terminator in it.

Outreach, Ethics and Marketing
I started of my day by exploring and getting familiar with the online virtual world called Second Life (TM). I attended a conference on the Science Centre Island. I browsed different ways for organizing the Ethics conference in Second Life.
For marketing, I did research on some more Oil & Gas companies starting off with Enbridge Pipelines and finishing off with Pajak Engineering. I e-mailed out newsletters to companies, updated our iGEM marketing list, filled out a grant application and printed posters for our Third University of Calgary iGEM Bake Sale. I also looked into potential organizations that would help us in our 2009 iGEM Education and Outreach Campaign. I have decided to contact the respective individuals as early as next week.

Revision of Restriction Digest and Phosphatase Treatment Activities
Phosphatase treatment is now being combined with the restriction digest activity so I moved some of the script that was within the recipient tube for restriction digest, into the phosphatase treatment script and had to add new sections to the recipient tube so that the product you receive has to be taken to phosphatase treatment manually, before an avatar may receive the proper product to begin construction. This required the new method of searching for inventory, which is much more effective.
I completed instructions for the bacterial transformation activity and it was discovered that some of the items our avatars were using for PCR were named incorrectly, which was causing some major issues with testing out the equipment so those items have been renamed and the machine is in the process of being test once again.
Communication between Objects
I was also able to test the DNA extraction activity and it functions correctly as long as you follow the instructions provided throughout the activity. To improve upon it, we will have to get the objects to communicate with each other, which I have now started and the constant messaging would have to be reset for all steps within the product tube.
Since I find that the restriction digest is not unique compared to the other activity, tomorrow I believe that instead of moving the tube form water bath to heating block automatically, I will:

Verification of the transformed reporter circuit
Now that hopefully the whole reporter circuit is transformed into TOP10 cells, I have performed a colony PCR of those colonies with Biobrick CP F/R primers and with the following conditions:
94°C for 3 min; 36x (94°C for 30s; 53°C for 45s; 72°C for 1 min and 20s;) 72°C for 10 min; held at 4°C.
Using Biobrick CP primers was a mistake, however, because I should have used Pqrr4 F primer and Biobrick CP reverse primer. This would have allowed me to verify whether or not Pqrr4 was not cut out during the construction. Another mistake was noticed, as I did not load any positive size control. Without any positive size controls to compare against, it is hard for me to tell whether or not it contains every piece of the circuit. Because of today's mistakes, I am planning to run another cPCR of the reporter circuit with 2 positive size controls, Pqrr4 by itself and Pqrr4 with B0034, and use Pqrr4 Forward and biobrick CP Reverse primers. The cPCR products were ran on 2% agarose gel, at 90 volts, and the following image is the picture of the gel. Figure 1. cPCR of Pqrr4+B0034(RBS)+K082003(GFP+LVA) 
Colonies 1 to 8 did not get amplified at all, and Colony 9 seemed to have been amplified, but not of the right size. The expected size is about 1043bp with some additional length added due to the primers annealing outside, and the band in Colony 9 lane is a bit higher than the expected size.
Modelling meeting
Anders, one of our facilitators, came and gave us an advise on modelling. We discussed about limitations, advantages of our characterization methods and what we should focus on.
Updated Wiki notebooks from May 26 to June 11
Because our wiki notebook page has been created recently by Mandy, we were not able to post our previous updates, so old updates are now being done along with the recent updates.

Second Life: Exploring Potentials of Seminars for Ethics
Today, I took Emily and Fahd to an in-world seminar being held by Science Enthusiasts regarding the value of interdisciplinary learning, and its contrasts from 'multidisciplinary learning'. While the topic of the seminar was related to our project (as we participate in exactly that), the main purpose of our exploration was to monitor good (and unfortunately, bad) methods of running talks and seminars in Second Life.
Through examination of the Interdisciplinary science seminar, we have observed that organized, directed talks with only invited guests (and then questions afterwards) would be more of use to us than complete open discussion (or perhaps half and half) as allowing open discussion of ethics, while valuable, allows for veering off-topic very easily. If we do decide to allow full audience participation, structured moderation of the topics would be necessary. During the seminar, I was also able to meet an educator by the name of 'Graham Mill', who is exploring the uses of Second Life in teaching Microbiology. He has heard of iGEM and expressed interest in our project. Although he is occupied for the next few weeks, I will be meeting him again to tell him more about what we are doing and see what he has done to teach microbiology in SL.
Revision of Notecard Prompts for Second Life Lab Missions
The three 'lab missions' that guide users through the lab section of our island are still in development. Today, I revised the information provided in the notecards, eliminating alot of specific talk about biobrick parts, as I hope to make a more thourough attempt at explaining biobricking in an 'earlier level' on our island: namely the base of the Biobricking Helix. To make experiments more comparable in length (and to reinforce the concepts specifically related to bacterial transformation, an important procedure), I have added steps to two of the lab missions.
With the help of Max Chatnoir, the creator of Genome Island, and Thane, I have begun thinking of the best (and simplest) way to define a gene and its function (likely through an analogy - such as computers). Thane is really good at analogies, let me tell you. Most of the time spent in second life were in the seminar and editting notecards. I've turned by DNA extraction activity over to Katie for fixing (as she is a master scripter and has figured out a way to solve my problem in which people can jump in at the end of the activity without doing anything at all. |

Technical Report writing for LuxO D47A
Today's update will not be as exciting as the last few days: it's amazing how much time goes into technical writing and condensing a few months of work into a few short sentences. I made a lot of progress on my discussion section after consulting with Thane on what content is appropriate to include. We have a nicely-referenced paragraph on where LuxO D47A fits into the greater scheme of our signalling and reporter circuits, and how it will be used in conjunction with LuxO D47E to test the latter.
Mathematical modelling meeting with Professor Nygren Our modelling team met with Thane and Prof Nygren to discuss our recent progress and later direction on the mathematical modelling front. We presented the aspects of the circuit that we plan to characterise, which we will reveal tomorrow in the handout that we have prepared over the last few days. I will spare you the gory details for now, but we're planning to explore static performance (including a colony range analysis and a curve fit to the Hill Equation), dynamic performance (time dependence of our system), response time (based on the dynamic performance) and robustness (in terms of varying the promoter strengths and the surrounding conditions). We will also explore other areas that might be worth testing for robustness, based on the literature and what we can predict from our model. Preparation of meeting handout We had prepared a short document outlining the areas of our circuit that we plan to characterise. I have cleaned it up a bit so that it is more suited for our lab meeting presentation tomorrow. As mentioned earlier, the contents will be revealed in detail tomorrow. |
