Uses: Tris-HCL buffer is not only widely used as a solvent for nucleic acids and proteins, but also has many important uses. Tris-HCL is used for protein crystal growth under different pH conditions. [3] The low ionic strength of Tris-HCL buffer can be used for the formation of the intermediate fiber of C. elegans nuclear lamin (lamin). [4] Tris-HCL is also one of the main components of protein running buffer. In addition, Tris-HCL is also an intermediate for the preparation of surfactants, vulcanization accelerators and some drugs. Tris-HCL is also used as a titration standard.
