Today I ran two trials of the buffer solutions for the "5mM" Cohex series. The results leave me a little skeptic that the DNA was actually precipitated in 5mM, because all of the buffer solutions contained pretty exactly 3mM. This would explain why the Mg values only range from 0 to 50, which was the same range used for the 2mM series last summer. I will look into the other buffer solution later this week, to see if it contains 5mM or 10mM.
