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.
What is the purpose of adding sodium azide to buffers? Must sodium azide be added to buffers when prepared by the user?
