Usage of Tris: Tris buffer solution has not only been widely used as solvent of nucleic acids and proteins, there are many other important uses. Tris has been used for the growth of protein crystal in different PH conditions. Tris buffer with low ionic strength can be used for the formation of the intermediate filament of nematordes (C. elegans) and lamin. Tris is the main component of protein eletrophoresis buffer. In addition, Tris is the intermediate for the preparation of surfactant, vulcanization accelerator and other drugs. Tris has been used as standard titrimetric substance.
