Sodium azide is usually used in buffers, etc., at a concentration of 0.1 to
0.2% to prevent microbial growth. People use azide because it does not
react with antibodies, nucleic acids, and other biological probes. Other
anti-microbial agents may contain detergents or other compounds that are
detrimental to experiments--so choose alternatives carefully.
