Phosphate buffered salts, Dulbecco's formula (DPBS) is a balanced salt solution (BSS) used for the handling and culturing of mammalian cells. DPBS is used to to irrigate, wash, and dilute mammalian cells.

• Clear, colourless solution format
• pH: 7,0 to 7,6
• Stored at 15 to 30 °C

Phosphate buffering maintains the pH in the physiological range. Calcium and magnesium facilitate cell binding and clumping. DPBS without these ions can be used to wash and rinse suspended cells.
