This morning I ran my samples in the Spectrometer. The pattern of my results looked good. The sample that contained Mg consistently had more Mg than the sample without Mg. The second sample contained less P which it was supposed to. However the data was consistently off by a factor of about 10. In the afternoon, I ran the excess liquid from the centrifuge in the second spectrometer to see where the nucleosomes went. Most fell out of the samples during the first spin.
