I have purified antibodies on a column and I would like to store them in a buffer containing sodium azide. I ordered the powder but reading the MSDS, it seems impossible to use it as it is incompatible with water and explodes. How do you do to put sodium azide powder in a buffer solution? Thank you in advance.
In our lab, to block internalization and endocytosis of EGFR, an inhibitor solution of 2 mM of sodium fluoride (NaF), 10 mM of sodium azide (NaN3) and 5 mM of 2-deoxy-D-glucose is used.

Sodium azide (NaN 3) is added to prevent microbial contamination. PBS with azide is also useful as a storage buffer. Ready to use PBS with Azide buffer is a solution with a phosphate buffer concentration of 0.01M, 0.027M potassium chloride, 0.137M sodium chloride, and 1.76 mM potassium phosphate with 0.02% sodium azide. pH 7.4 ±0.2 (25°C).
The osmolarity of solution typically matches that of the human body (isotonic solution). PBS can act as a diluent for many experimental preparations and is non-toxic to cells. This preparation contains 0.1% sodium azide as a preservative and is 10X concentrated to …

I'm quite sure you meant alkaline iodide sodium azide solution. The preaparation of this reagent is given here:. To prepare this reagent, take 700 g of potassium hydroxide/500 g of sodium hydroxide and add 150 g of potassium iodide/ 135 g of sodium iodide and dissolve in freshly boiled and cooled water and make up tp 1000 ml.
0.05% sodium azide (preservative) 0.01M PBS, pH 7.2-7.4 Mix well and store at 4 ºC. Note: Do not use it to dilute HRP conjugated antibody as the sodium azide is inhibitor of HRP. Do not use it to dilute Alkaline Phosphatase (AP) conjugated antibody as the phosphate in PBS is an inhibitor of AP.
Phosphate-buffered saline (abbreviated PBS) is a buffer solution commonly used in biological research. It is a water-based salt solution containing disodium hydrogen phosphate, sodium chloride and, in some formulations, potassium chloride and potassium dihydrogen phosphate. The buffer helps to …
So my co-workers and I were wondering why FACS buffer seems to always include FBS, which necessitates the use of sodium azide as a preservative.
