PBS (phosphate buffered saline) is a common buffer solution used in the laboratory. It is an isotonic and non-toxic buffer that is meant to mimic the osmolarity and ion concentrations of the human body. PBS is used for immunoassays, for sample dilution, for protein purification, and as a wash buffer in cell cultures. PBS tablets are premeasured tablets for convenient preparation of 1X PBS solution at a pH of 7.3 – 7.5. PBS buffer contains 10mM phosphate buffer, 137mM sodium chloride, and 2.7mM potassium chloride.

Each tablet prepares 100 mL of a 1X PBS solution.
