Why sodium azide is used in the antibody?
Sodium azide is a preservative often used in antibody solution. It prevents bacteria from growing in the serum. If you are planning to use the serum directly in cell culture, please notify us. For cell culture usage, sodium azide should not be added to the serum. On the other hand, if your serum contain sodium azide, it can be easily removed by dialysis. Alternatively, Proclin300 can be used in place of sodium azide.
