Phosphate Buffered Salts, Dulbecco's Formula, without Magnesium and Calcium
Cell Culture Media

Role of a balanced salt solution in cell culture is multifaceted and can be divided into four principal functions: 1. Serves as an irrigating, transporting and diluting fluid while maintaining intra- and extracellular osmotic balance; 2. Provides cells with water and certain bulk inorganic ions essential for normal cell metabolism; 3. Combined with a carbohydrate, such as glucose, provides the principal energy source for cell metabolism; 4. Provides a buffering system to maintain the medium within the physiological pH range (7,2 to 7,6).


  • 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 irrigate, wash, and dilute mammalian cells
  • 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


Inorganic Salts: Potassium Chloride [KCl]: 200,0000 mg/L; Potassium Phosphate Monobasic [KH₂PO₄]: 200,0000 mg/L; Sodium Chloride [NaCl]: 8000,0000 mg/L; Sodium Phosphate Dibasic [Na₂HPO₄]: 1150,0000 mg/L
