The primers have been designed the parts have been ordered and a plan has been put together. Now its time to start construction right? Wrong! All of these parts and ideas have to be thoroughly tested. We need to make sure that all the parts we've ordered are what they're supposed to be, where they're supposed to be and do what they are supposed to do. Tedious I know...
This portion of our project provided unique challenges for a couple of reasons, which we are going to outline here so that anyone attempting to repeat our project won't have to deal with the same intense frustration and agony we did. Aren't we nice?
Some of our bigger challenges in the testing phase...
- Ok, first of all. When we ordered our initial batch of parts from MIT we tried to start working with them right away. This was not a great idea as full descriptions of each parts coordinates on the plates were not readily available from the registry. This lead to a brilliantly doomed attempt at reverse engineering the part locations. Things never really worked out with this plan unfortunately, did I mention it was brilliantly doomed? So The lesson is to be very careful with the parts you have ordered and take the time to work with the registry and ensure that you know 100% where everything is and how it is labled. Learn from us... seriously
- Our second major hurdle had to do with our TOP10 cells. These are cells that are competent to be transformed in our crazy biological experiments, in case you didn't know. We were having some real trouble with some of our constructions, getting full lawns of cells after a ligation. Now this would be excellent, were it not for the sheer overwhelming odds that something was going seriously wrong. After 3 weeks of testing everything and anything we found that our cells, for some reason, had an innate resistance to chloramphenicol. This was a huge issue as most of our test plates contained chloramphenicol which we were using as a selection pressure. So while the odds of this happening are unlikely keep in mind this could be one of the problems you may face.
- Third major issue came with one of the pivotal parts of our system, the light sensor. The registry part, M30109, is based off of the light sensor plasmids developped by the Austin iGEM '05 ad '06 teams. This part consists of the three seperate genes, which should form a working light sensor when transformed. Our current theory (as put forth by Patrick King) is that there may be a mutation at one of the biobrick restriction sites that prevented us from being able to isolate the part from its plasmid backbone. The biobrick primers we use also anneal at the biobrick restriction sites, and our attempts to PCR out the part were also unsuccesful. So we spent a few agonizing months trying to figure out why the part would not cut, and would not replicate in PCR, the way it should. Eventually we resorted to contacting the texas team and asking them for the two plasmids from their original project. It was here that we were informed of a potentially significant issue.
