Applications and Usages
1, Tris buffer, only nucleic acids and proteins are widely used as solvents.
2, Tris is used for protein crystal growth under different pH conditions.
3, Tris buffer having a low ionic strength can be used nematode (C. elegans) is formed lamin (lamin) intermediate fibers.
4, Tris is a major component of protein electrophoresis buffer.
5, Tris for the preparation of a surfactant, a vulcanization accelerator, and some drug intermediates.
6, Tris titrated also used as standard.
