Product Description
Phosphate buffered saline (PBS) with EDTA is commonly used in biological research. The buffer's phosphate groups help to maintain a constant pH. The osmolarity and ion concentrations of the solution usually match those of the human body (isotonic). PBS contains 1mM EDTA at final 1X working concentration, is used to disengage attached and clumped cells. Divalent metals such as zinc, however, cannot be added as this will result in precipitation
