Tris acetate is a white, crystalline, powder with a faint vinegar odor. Tris acetate, or tris(hydroxymethyl) aminomethane acetic acid salt, is a is highly soluble ammonium salt commonly used as a biological buffer ingredient biological, medical, and biochemical processes. One such process requiring pH control with tris acetate is the DNA extraction. DNA extraction is a pH-sensitive process which uses tris acetate buffer to keep the pH stable between pH 7 and 9. Tris-acetate is also used to prepare TAE buffer (tris-acetate-EDTA), which is used as a running buffer for DNA agarose gels.
