Sodium+Azide

Preventing contamination with sodium azide
To prevent microbial contamination, sodium azide can be added to an antibody preparation to a final concentration of 0.02% (w/v). Many Abcam antibodies already contain this preservative at concentrations ranging from 0.02 to 0.05%. This will be indicated on the datasheets in the section titled “Storage buffer”. source: http://www.abcam.com/index.html?pageconfig=resource&rid=10795
