Phosphate Buffered Saline (PBS) is a common buffer extensively used in molecular biology, cell culture and biochemistry as it can maintain pH and osmolarity.
10X PBS (Endotoxin Free) is a water-based salt solution containing Sodium chloride, Sodium phosphate and Potassium phosphate. This solution is extensively used in molecular biology, cell culture and biochemistry for maintaining the physiological pH and osmolarity. 10X PBS (Endotoxin Free) is isotonic and It is also used as a wash solution and for diluting antibodies during western blotting and immunohistochemical staining.
