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 mixing two stock solutions.
A buffer solution is a solution where the pH does not change significantly on dilution or if an acid or base is added at constant temperature. [1] Its pH changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical ...

The Britton–Robinson buffer (BRB or PEM) is a "universal" pH buffer used for the pH range from 2 to 12. It has been used historically as an alternative to the McIlvaine buffer , which has a smaller pH range of effectiveness (from 2 to 8).
Smears are air dried between 10 and 60 minutes, fixed in 80 vol% ethanol for 5 min at 20-22 °C, rinsed with tap water, and air dried. Films are then immersed in the citrate-phosphate buffer for 5 minutes at 37 °C and gently agitated for about 3 minutes.
