A Day Full of Research
Today was the first day that we were able to devote the entire day to research. It was a very valuable day, as we were able to play around with the FITC and the nanodrop machine, both of which are fairly new to us.
We began the morning by making 2 sets of gels that used the FITC instead of the dye (which we had been using prior to yesterday). We then were able to test it using the nanodrop to see the rate at which the FITC was leaving the gels. Because the dye that we had been using acts differently than the FITC does, we are not yet sure what concentration of FITC to use such that the nanodrop picks it up. Thus, we experienced a lot of frustration today, as the various levels of FITC barely registered on the machine. We are also still getting used to working the nanodrop and the pH meter, but I think we are almost proficient at both!!
Nearly panicking, we realized that we had run out of our prepared FITC solution in the middle of making a set of gels. We had to rush to measure out the powder, dissolve it, and neutralize its pH before our gels started to set. This taught us to be more careful in the future. The biggest issue that we ran into today was that we didn’t make the FITC solution strong enough. This may be hard to explain, but we account for the dye we put in the gels by subtracting from the water that we were supposed to put in. The rest of the time that we have been working with these gels, we have never wanted to add more dye than water, but today, we wanted to add more FITC solution than we were able to given the total amount of water. Thus, we recognized that the next time we make the FITC solution, we will have to make it stronger than we did today. Luckily, we have not yet approached the saturation point (and we are not that close to approaching it either!!).
Additionally, we have had the issue of having to wait a long time in between readings because the collagen concentration is pretty high. Therefore, we have decided to try to make the gels with a lower collagen concentration, so that we will hopefully see some movement of FITC if we test the gels every 15-20 min or so. There is so much more to test! I hope we don’t run out of time and/or materials.
Our project is getting more and more exciting as we go along. One thing that we noted today is that we’re having a lot of trouble with getting some of the readings to work out as we know that they should. We mused over how difficult/unclear our results would be if we didn’t have an idea of how they were supposed to work out. This really makes me respect researchers like Millie (our professor) and her team for the amount of background information that they must know, not only to motivate the research and experiment, but also to carry it out and give it the right direction. It’s such a pleasure to be working with them! Really being able to get in there and use all of these materials and run all these tests can be monotonous at times, but it has really been able to raise my interest in the subject matter. It allllllllllllmost makes me question my choice of career, but I’m not sure that I could ever come up with my own research project, and I don’t think I would be content to work on someone else’s project in the long term. I guess, in a way, teaching seems like my own project, so I’m pretty sure that I’m in the right place.
