Tris(hydroxymethyl)aminoethane

Tris buffer is not only widely used as a solvent for nucleic acid and protein, but also has many important uses. Tris was used to grow protein crystals at different pH conditions. The low ionic strength of Tris buffer can be used to form intermediate fibers of lamin of C. elegans. Tris is also one of the main components of protein electrophoresis buffer. In addition, Tris is an intermediate for preparing surfactants, vulcanization accelerators and some drugs. Tris is also used as titration standard.
