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
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 .
Phosphate Buffered Saline (PBS) is a solution prepared by diluting a stock solution of specific salts (NaCl, KCl, Na2HPO4•H2O, KH2PO4) to create a buffer with a pH of 7.3. Tween 20 is added to PBS in concentrations between 0.1% and 0.2% to optimize its performance in biological applications.
Measuring analyte concentration using serial dilutions and standard curve. Phosphate buffered saline , more commonly known as PBS, is one of the most commonly used buffers in different biological research applications for maintaining the pH of a solution.

28 sty 2019 · 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.
