Looked at Papers
Potential :
Found a paper that did deterministic modeling . The paper looks at the autophosphorylation of LuxN ... using as a model for something similar like (LuxPQ) ??? Solution is very complex . If this model will be used---- need to find a simpler way to solve using matlab
More deterministic stuff : Quantitative analysis of protein- protein interactions Sensitivity amplification in Phosphorylation-Dephosphorylation cycle
Design and sigmalling mechanism of light regulated histidine Kinases Biological pathway kinetic rate constants are scale invariants Gauntlet replied back : They are thinking and will get back to me on the article idea for the frosh supplement

Marketing for July 15th 2009
Today, I concentrated my energies at marketing our iGEM project. Here is what I did today:

Construction of PQ-B-R-OU-B into AC plasmid
Purpose: To construct the signaling circuit by inserting PQ into B-R-OU-B in AC plasmid, as the pCS26 vector has Kan resistance. This was done by (1) cutting the insert (PQ) with EcoRI and SpeI, and cutting the vector with EcoRI and XbaI, as well as (2) attempting a PQ-B-R-OU-B plasmid switch of colony 12 (see July 14) from AK to AC by cutting the insert and AK plasmid both with XbaI and PstI. After this restriction digest, phosphatase and ligation treatment was performed and the plasmid was subsequently transformed into TOP10 competent cells and plated overnight on LB+Chlor.

Insert Intuitiveness
The main goal I made for myself today was to make the activities I am scripting much more intuitive (especially for first-time second-lifers) then they already are since I believe they seem simple to me only because I was the one who made them. To do this, I have started to create instructions for restriction digest that are not contained within a notecard, which some may be inclined to pass over. So now when the instruction label is clicked (just below the writing – Restriction Digest Start) it will now explain what each section of the activity is for and what you can do (It also lights up each section being talked about to draw the eye), but I would like to improve upon this by adding more detail. They will also get a notecard that explains the restriction digest, ligation and phosphatise treatment aspects of the entire molecular cloning activity.
I also completed the script for a general activity for bacterial transformation so now it will quiz you each time you put a certain object into the tube’s inventory and the questions will relate to the item you added. It then keeps track of the number of questions you answer correctly and if you answered all of the questions right, your competent cells were successful in up taking the DNA. I believe I will make this activity a gradient for now so as long as eight or more questions were answered correctly, the competent cells will survive on their respective plates, just at different levels of growth. I am unsure if I should keep track of each avatars score, though I believe it is possible since I have seen this used other places for different reasons, but it would prevent someone taking credit for someone else’s work. Questions include: What temperature do competent cells need to be stored at?, What does it mean for cells to be competent? etc. Now I am back to looking at the activities that I began two months ago and am now updating them to suit the lab activities. I have started and will continue tomorrow:

2. cPCR of Pqrr4+I13500
Since yesterday's cPCR only yielded one possible colony that may contain the circuit of interest, today I performed cPCR on more colonies to see if I can get more to ensure that what I have is what I want. A total of 11 colonies were picked and cPCR was done on then using BBK CP F/R primers. The following is a picture of the gel:
The colonies 2, 3, 7, 9, 10, and 11 seems to have worked. Contamination in negative control, and nothing in positive control. Perhaps the tubes were switched around. Overnight cultures of yesterday's Colony3, today's colony 2, 3, 7, 9, 10, and 11 were grown for tomorrow's restriction digest.
2. Transformation of B0034 and E0422
For future needs, I need to take B0034 (RBS) and E0422 (RFP:LVA+Term) out of the 2009 igem distribution plates. B0034 is needed because I need to construct Pqrr4+RBS+GFP:LVA, but the part with GFP:LVA does not contain RBS. E0422 may be needed for characterization. B0034 and E0422 were thus taken out of the plates and transformed into TOP10 cells. They were then grown overnight. Carol promised to take the plates out tomorrow.

DNA Extraction in Second Life
Today, I continued on with scripting DNA extraction (and still am not done :( ). I kept the centrifugation at each step, so I had to script the centrifuge to work with different ‘solutions’ and make the test tubes and other components move to and from the centrifuge smoothly. I wasn’t able to script the centrifuge door to close when it was being used, so it has to be manually done by the user. I rewrote the addition of buffer part so that centrifugation is required after each step. I had to rewrite most of the scripting I did yesterday due to the centrifuge part, but right now it all works up to the steps that require addition of buffer, which I still have to finish.
The Linden in charge of education hasn’t replied to our message yet, so if he doesn’t by the end of the week, Stefan and I will visit him during his office hours on Tuesday.
Tomorrow I hope to complete more of DNA extraction (which is taking me longer than it should) . I also have to add variations to it, as right now, it is just the script for a general genomic DNA extraction. These specific variations will be used for the lab missions itself. The general components of lab are just to play around for those who are curious about only particular things, while the specific lab missions have specific goals and completing all 3 will require using each piece of equipment at least once.

Names and Commas
Retrospective Notebook: This entry was not written on this day, but derived later from working notes I made that day.
Began working on putting the important DNA part information into the object's names. Briefly toyed with the idea of making all complexes (be they protein, DNA, small cofactors, or any combination of the above) user definable, before determining that this would be extremely difficult. Began thinking about how the Biobricker and its construction feature would work exactly, what types of information would each would need from the other.

Marketing, media and advertisements
For marketing:
I called these companies again today:
Company 1 – filled out online application for sponsorship so follow up phone call July 20th
BioAlberta –I called to follow up but he wasn’t there so I left a msg and sent him an email.
Company 3 – they received our package and looking through , follow up July 24 Company 4&5 : follow up july 24 – received our package Company 6 : finally got a hold of them, wanted our sponsorship pkg so I sent it to them Company 7 – sent our sponsorship package by mail follow up at the end of July Company 8 – sent sponsorship package on Monday, called today to follow up – couldn’t get a hold of the CEO so call back tomorrow Company 9, 10, 11 : received sponsorship package so follow up July 20 Found 10 more biotech companies online who we could contact. So I assigned and distributed the new list of companies to the rest of the marketing team! :D I wrote up 3 short articles for the July newsletter (Lethbridge workshop, 3rd bake sale, Sponsor of the month). Went to visit Leanne Yohemas (Senior Communications Leader – Dept. of Science) – she said she can put up iGEM on the UC twitter and Bio Sci newsletter if we write up an article. She even volunteered to edit and review our articles. We’re thinking of giving her our rough draft in the first week of august. She said she’s willing to be our mentor for promoting iGEM. She also gave us the contact info of the Bio SCI newsletter’s journalist and for the leader/VP of Research in Action (newsletter). Lastly , she gave us the contact info of the person who we should approach for contacts of UC Alumni for funding purposes!! This person is from Development- from the Faculty of Science. I’ll contact her tonight!

Variety of things to do
so what am I doing today?

Technical report writing
This didn’t happen the way it was supposed to. I have been building a repository of papers that either focus on quorum sensing (so lots of Bassler and other papers that reference her heavily) or on synthetic biology/biobricking so that I could get a sense of how to structure this. I ended up on a paper by Endy and what looks like 2 of his students that describes their characterisation of the BBa_F2620 part. And once I saw this, that part of modelling took over my life. I sent the paper out to the crew and cc’d the two of you – an explanation of my plan is in my email, but I want to look through it and see what we can easily implement in our work. Because the closer we can mirror this in our circuit characterisation, the better! They seemed to use FACS a lot in their analyses for determining genetic stability. Will we have access to the same technology? Or is there a sneaky way to circumvent it – say, by making a few overnight plates and taking a ratio by sampling the cultures that grow? Anyhow, I shall look at this more tomorrow – I have the paper and the supplement printed, and it would be a good idea to have our experimental procedures ready for this step so that we can hit the ground running when we start.
Modelling effort coordination
This wasn’t a huge deal – we just had Chinee update the reaction rule chart that we made on Friday, so that the reaction constants that we’re looking up are laid out in front of us on one convenient table. It’s so easy to lose sight of why you’re reading a paper, so this will be useful in helping us keep our goals in mind and in working efficiently.
Plate reader
I didn’t get around to this and I didn’t want to just start messing around with it without you guys there. If we do end up doing data-based modelling, we will need to have a sense of our delay (time between input and output measurement corresponding to that input). We want this delay to be as low as possible, especially if we’re worrying about protein degradation and time-dependent data (such as response time) – so it would be very prudent to plan our experiments around making that happen. Of course, if the plate takes a long time to read but the reactions are very slow, it won’t be an issue – you just don’t want to lose too much useful information while waiting for the plate measurements to occur.
