Webjusted low media pH use citric acid as part of the citrate phosphate buffer system (CPB) also known as McIlvaine buffer [20]. CPB is practical for media development for two reasons: first, the tri-protic nature of citric acid and disodium phosphate with three pKa values each, allows to buffer across a wide range of pH values (pH2.2 to pH8.0). McIlvaine buffer is a buffer solution composed of citric acid and disodium hydrogen phosphate, also known as citrate-phosphate buffer. It was introduced in 1921 by the United States agronomist Theodore Clinton McIlvaine (1875–1959) from West Virginia University, and it can be prepared in pH 2.2 to 8 by … See more McIlvaine buffer can be used to prepare a water-soluble mounting medium when mixed 1:1 with glycerol. See more Preparation of McIlvaine buffer requires disodium phosphate and citric acid. One liter of 0.2M stock solution of disodium hydroxyphosphate can be prepared by dissolving 28.38g of disodium phosphate in water, and adding a quantity of water sufficient to make … See more
