Balanced Salt Solution (BSS), also called Physiological Solution, is a combination of the buffering capacity of a buffer, the isotonicity of a physiological saline solution, and the nutrient supply characteristics of a culture medium. It has the functions of maintaining osmotic pressure, keeping pH stable, and providing simple nutrition, and can meet the basic needs of survival and metabolism of tissues, organs, or cells in in vitro experiments. Some balanced salt solutions also add a small amount of phenol red to indicate changes in the pH of the solution.
Phosphate-Buffered Saline (PBS) is the most widely used balanced salt solution in biochemical research. Its main components are Na2HPO4, KH2PO4, NaCl, and KCl. PBS buffer is often used for rinsing tissue blocks, washing cells, transporting cells or tissues, preparing other reagents, and as a diluent for cell counting.
