Dulbecco's Phosphate Buffered Saline (DPBS) is intended for use in the maintenance of mammalian cells where a chemically defined, balanced salt solution provides an environment that will maintain the structural and physiological integrity of cells in vitro. DPBS is commonly used in cell enumerations as a diluent, for rinsing cells and as a buffer in many chromotographic procedures. DPBS also is used to wash and resuspend cells during the dissociation process.
