The sodium azide is a preservative preventing the microbial growth in the buffer. It can be excluded from the buffer without affecting the performance of the assay. Please note that if the azide is not included the buffer will not be as stable as stated in the data booklet.
Must sodium azide be added to buffers when they are prepared? Can buffers be prepared without azide?
