PBS buffer solution

Phosphate salt solution (PBS) with buffer properties is mainly used to wash and maintain the physiological balance of cells. The duration of keeping cells in the buffer is a few minutes and a maximum of several hours. Buffers are also used to adjust osmolarity. Phosphate salt solution with buffering properties is used in cell counting as a diluent for washing cells and as a buffer in many chromatographic processes. Phosphate salt solution (PBS) does not contain bicarbonate and is more sensitive to pH changes.
