PBS [1X] [137mM NaCl, 2.7mM KCl, 10mM KH2PO4, 1.8mM NaH2PO4, pH 7.4]



General description

PBS (phosphate buffered saline) is a balanced, isotonic salt solution used for a variety of cell culture applications, such as washing cells before dissociation, transporting cells or tissue, diluting cells for counting, and preparing numerous reagents. Generally used in biological research, this water-based salt solution consists of disodium hydrogen phosphate, sodium chloride and, in some preparations, potassium chloride and potassium dihydrogen phosphate.


Phosphate Buffered Saline (PBS) is supplied in a 1X concentration.
