Phosphate-buffered saline (PBS) is a buffer solution used in biological research. It is a waterbased salt solution containing Sodium Phosphate, sodium chloride and Potassium Phosphate. The osmolality and ion concentrations of the solutions are non-toxic to most cells.

PBS is used in cell enumeration as a diluent, for rinsing cells and as a buffer in many biochemical/cellular assays. PBS is also used to wash and resuspend cells during the dissociation process. This product has neither Calcium nor Magnesium ions in its composition.
