[Microcalorimetric study of thermodynamic values of aqueous phase transition and eutectic melting in the binary and ternary systems Na-DNA--H20 and Na-DNA--H20--NaCl].
Thermodynamic parameters of water phase transition and eutectics melting in DNA water-salt solution were studied by means of low temperature scanning differential microcalorimetry at different concentrations of polyanions. DNA hydration was measured and the character of changes in Na+ counterion binding was revealed during the transition of double helix into the state of random coils.
