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.

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.
1. Phosphate buffered saline (PBS) is used to clean samples. 2. Buffer A (20 mM tricine and 250 mM sucrose, pH 7.8) is used to protect intracellular organelles in the sample homogenization. 3. Buffer B (20 mM HEPES, 100 mM KCl, and 2 mM MgCl 2, pH 7.4) is used for washing the isolated LDs. 4.
Phosphate buffered saline (a.k.a PBS or PBS buffer) is one of the most used buffers since it is isotonic to most of the cells. We have placed reagents required for preparation in a table. This table also contains information on molarity of each reagent and amount of salt (s) to be added for making 500mL and 1L of 1X and 10X.
