10X PBS pH 7.2 with Azide

Phosphate Buffered Saline (PBS) is a regularly used buffer in biological research. The phosphate ions help maintain a constant pH around neutral. 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 be diluted 10-fold to the working concentration. Phosphate Buffered Saline 10X pH 7.2 with Azide (0.2 M Potassium Phosphate 1.5 M Sodium Chloride 0.1% (w/v) Sodium Azide) is a concentrated stock solution and should be diluted appropriately with distilled, deionized water or equivalent to its final working concentration. 10X PBS pH 7.2 with Azide is meticulously prepared using ultra pure reagents dissolved in highly polished pharmaceutical grade deionized water.
