WebPhosphate buffered saline (PBS) Commonly used in biological applications, PBS is a water-based salt solution with a simple formulation. It is isotonic and non-toxic for most cells. It includes sodium chloride and phosphate buffer and is formulated to prevent osmotic shock while maintaining living cells’ water balance. Phosphate-buffered saline (PBS) is a buffer solution (pH ~ 7.4) 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 maintain a constant pH. The osmolarity and ion concentrations of the solutions match those of the human body (isotonic).
