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.
Is it necessary to add sodium azide to the sodium maleate buffer used in the Resistant Starch Assay Kit (K-RSTAR)?
