Citrate-Phosphate Buffer (0.15 M, pH 5.0) Preparation and Recipe

A traditional buffer originally introduced in 1921. Since the Citrate-Phosphate buffer (also known as the McIlvaine buffer) only has 2 ingredients, the recipe can be adjusted to a pH range of 3-8. It is used for multiple applications in cell biology, molecular biology, and hematology.
