About Sodium Chloride, Molecular Biology Reagent

Sodium chloride is used in a wide variety of biochemical applications, including intravenous fluids (normal saline is 0.9% w/v in water10), density gradients3,6, a diluent to increase ionic strength in buffers or culture media and in salt-out procedures in the isolation of DNA.8 It has also been used in high concentrations for preservation of foods since bacteria cannot grow in high salt conditions. A salt-ice mixture in the ratio of approximately 33 g sodium chloride to 100 g ice (at -1C) will drop in temperature to as low as -21C, depending on the rate of stirring and the size of the ice chunks.
