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.
Phosphate buffered saline (PBS) is a buffer solution commonly used in biological research. PBS is isotonic and non-toxic to cells. It is used in several applications of tissue culture, most notably for cell washing and trypsinization.
PBS is a balanced saline solution that will be used to wash cells to maintain osmotic balance between internal and external environment of cell. From: Methods in Cell Biology, 2023

PBS or phosphate-buffered saline is a buffer solution that is particularly valuable because it mimic the ion concentration, osmolarity, and pH of human body fluids. In other words, it's isotonic to human solutions, so it's less likely to cause cell damage, toxicity, or unwanted precipitation in biological, medical, or biochemical research.
