Week 1 Day 3

This morning we continued to make our calibration samples.  I had a lot of trouble getting the correct amount of phosphorus, since it was such a tiny amount to measure.  I had to do one of the samples 4 times before I got the amount of phosphorus at a reasonable percent error.  Then I helped brian make one of his samples that he was having trouble with as well.  After lunch, we calculated the adjusted concentrations in our calibration samples.  Then we read about and learned about the computer program and the spectrometry machine we will be using to analyze samples throughout the summer.  Finished up with the day with a meeting with Prof. Andresen about the actual projects we will undertake this summer.  Mine is a continuation of his previous research.  Basically figuring out whether or not the tails that come off of nucleosomes are wrapped or not.  I will be working on getting those error bars down to reasonable sizes.
