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.
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.
PBS is an isotonic buffer frequently used in biological applications, such as washing cells, transportation of tissues, and dilutions. PBS closely mimics the pH, osmolarity, and ion concentrations of the human body. Since it is nontoxic to cells, it is extensively used for cell container rinsing and other preparations that might leave a residue.
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 .
