Today I ran another competition between Ben and Fash, aiming to hone their pipette and calibrating skills. I also read a paper on DNA counterions. This paper suggested that counterions can contribute to the macroscopic properties of DNA solutions, such as osmotic pressure. It said that at High DNA concentrations, the counterion contribution to osmotic pressure prevails. Also, this paper suggested that there was a certain DNA/SAlt concentration range where osmotic pressure was proportional to the DNA concentrations, and independent of the salts.
