There are several methods make PBS. Some methods not contain potassium while others contains calcium or magnesium. Most common method is given below.
10 L stock of 10 x PBS prepared by dissolving following ingredients-
800 g -NaCl (Sodium chloride)
20 g -KCl ( Potassium chloride)
144 g -Na2HPO4 · 2H2O (Disodium phosphate) (DSP)
24 g- KH2PO4 (Potassium dihydrogen phosphate)
8 L of distilled water.
After complete addition and mixing, make up to 10 L. The pH of the 10 X stock is around 6.8, but when it diluted to 1 x PBS it should be changes to 7.4. While preparing buffer solutions keep in mind that measure the pH using a pH meter. If needed pH should adjusted using HCl or NaOH.
Upon the dilution the resultant 1 x PBS is with final concentration of 137 mM NaCl, 10 mM Phosphate, 2.7 mM KCl, and a pH of 7.4.

Phosphate buffered saline (PBS) is a buffer solution commonly used in biological research. The buffer helps to maintain a constant pH. The osmolality and ion concentrations of the solution usually match those of the human body. A) You need to prepare a stock solution at pH 7.00 with KH2PO4 and Na2HPO4 (pKa =7.21). What would be the respective concentration of these substances if you wish to obtain the final phosphate concentration [HPO4 −2 ] + [H2PO4 − ] = 0.3...
