Phosphate buffered saline (abbreviated PBS) is a buffer solution commonly used in biochemistry. It is a salty solution containing sodium chloride, sodium phosphate and in some preparations potassium chloride and potassium phosphate. The buffer helps to maintain a constant pH. The concentration usually matches the human body (isotonic).
