Acetate Buffer (pH 3.6 to 5.6) Preparation and Recipe
Sodium acetate buffers are used for purification and precipitation of nucleic acids, as well as for protein crystallization and staining gels used in protein electrophoresis. It is very popular in hematology, since there is some evidence that acetate-buffered infusions show improved stability. Acetate buffers are inexpensive and simple to prepare, and can be stored at room temperature.
