Today, I decided to try to redo my experiment but with different concentrations of MgCl. After making the samples, the concetrations are 0, 1, 10, 12, and 50 mM. I ran out of nucleosomes while making the last sample so sample 3 has only 15 microliters of NCP rather than 41. After making the samples, I spun them and pipetted out the top and bottom into separate tubes. I am ready to run the samples again when we have gas.
