Tris Base, 600-127

Tris base (not Tris alkali), also known as tris(hydroxymethyl)aminomethane, is widely used in biochemistry and molecular biology to prepare various buffers. For example, Tris‑EDTA (TE buffer) is commonly used for nucleic acid purification and storage, protecting nucleic acids from nuclease degradation. Tris acetate‑EDTA (TAE buffer) and Tris borate‑EDTA (TBE buffer) are routinely used for gel preparation and electrophoresis.
