The films were<br>obtained from solutions of calf thymus Na-DNA salts with a concentration of 0.2 mg / ml in 10 mM<br>solution of NaCl, as well as with different combinations: 10 mM NaCl and 10 mM Tris; 10 mM NaCl and<br>1 mM EDTA; 10 mM NaCl, 10 mM tris and 1 mM EDTA. Accuracy of temperature stabilization is<br>0.5 ÂșC, error of relative humidity determination is 2-3%. Films from solutions of Na-DNA with the<br>addition of 10 mM NaCl and 10 mM Tris and films obtained from solutions of Na-DNA with the addition<br>of 10 mM NaCl and 1 mM EDTA do not have the textures on the surface after drying. The films obtained<br>from the Na-DNA solution (at a concentration of 0.2mg/ml), 10 mM NaCl, 10 mM Tris and 1 mM EDTA<br>give textures similar to cholesteric spherulite textures, which are fully manifested in 40-50 hours after<br>removal of films from the camera</p&gt;}, number={27}, journal={Biophysical Bulletin}, author={Glibitskiy, G.
