Script:
Slide 1: - Introduce the team (i.e. collaborative effort between UofT and UW) and mention the project we're working on.
Slide 2: - Explain what makes this thermometer unique from all other existing models as in other models may limitations to where/how they can be used - size of the species of interest may be too small - research experiments where chemicals, radiation may be toxic for a colony but temperature readings are needed
- A bio-synthetic thermometer may be a possible solution to overcome these obstacles.
- Applications: - use to detect small changes in temperature in very small organisms- we can do this by measuring the intensity of the colour emitted - experiments or places where a quantitative reading cannot be obtained (i.e a person can not physically be there to take the reading (in anaerobic conditions?)) or where air pressure - may also use this to monitor temperature of aquariums using zebra fish for example
Slide 3: - Explain diagrams
Slide 4: - Explain our approach: how we decided to ligate parts separately and build up to the final product - Constructed many new parts - Replaced our cI repressor system with tetracycline repressor (tetR), an analogous system to cI but less leaky and can control externally
Slide 5: - Testing Phase - Intro: - Testing was split into 3 modules. - Each module acts as a checkpoint for a particular milestone in the construction process. - After each module we can ensure a vital component of the construct is functional. - State the goal/purpose of each module and how it was executed.
Slide 6: - Test Results
- Tested the intermediary pBad/araC + LacI ts coding sequence (R0011) + reporter gene thoroughly - We ensured that module 1 tests passed before continuing construction.
Slide 7
Conclusions/Results!
- Does it work/or not?
- What we learned from constructing the device
- at the beginning, we tested all enzymes for functionality via test plasmid + running a gel - while doing this we learned that Xba1 works slower than EcoRI, SpeI, and PstI
- Team communication, allocate more time for testing in addition to construction/designate a test team
- Limitations to the device
- can only detect temperatures in a small range
- does fluorescent protein stay? or decay quickly? ask Charles/Andy
- Experiments involving radiation - this thermometer cannot be used as the radiation will damage the DNA
- Expression of the reporter gene must be as sensitive as the activation of the transcription factor (for accuracy in timing events dependent on temperature and time)
- Future work that can be done to improve the device/design for next year
- investigate repressors etc that would be good for larger temperature ranges
- this would increase the application of the device allowing it to be another alternative to detecting temperature changes in biological systems.
