Trishydroxymethyl aminomethane
Basic Information
Name: Trishydroxymethyl aminomethane
Anther name:TRIS
CAS No.:77-86-1
Molecular weight:121.14
Molecular Formula:C4H11NO3
Appearance and character
White crystalline particles.
Application:
Tris buffer is not only widely used as a solvent for nucleic acids and proteins, but also has many important uses. Tris is used for protein crystal growth under different pH conditions. The low ionic strength characteristics of the Tris buffer can be used for the formation of intermediate fibers of the nematode (C. elegans) lamin. Tris is also one of the main components of the protein electrophoresis buffer. In addition, Tris is an intermediate in the preparation of surfactants, vulcanization accelerators, and some drugs. Tris is also used as a titration standard.
