Tris buffers comprise buffers based on the chemical compound Tris (tris(hydroxymethyl)aminomethane) and are often used in biological applications. Among the most widely used examples are Tris-Hcl (Tris hydrochloride), Tris-EDTA (TE), Tris-buffered saline (TBS), Tris-acetate-EDTA (TAE), and Tris-borate-EDTA (TBE). Tris buffers are used in maintaining a stable pH ranging from 7-9 for a number of experimental workflows, including electrophoresis, nucleic acid and protein purification, cell culture, sample storage, and more. Reagents are available from different suppliers and are offered in solid powder or ready-to-use liquid formats.
