Uses of Biology: Tris base, also known as THAM, is widely used as a biological buffer or as a component of buffer formulations such as TAE and TBE buffers. Tris has a pK_a of 8.06 and is very useful in the biology and biochemistry lab because it has buffering capabilities in the range of the typical physiological pH of most living organisms (pH 7.0-9.0). Tris has been reported to interfere with the activity of a number of enzymes, it should therefore be used carefully when studying proteins.

Uses: 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.

Uses: tromethamine can help mask odor in a formulation. It is also used as a buffer, keeping product pH stable.

Uses: In the synthesis of surface-active agents, vulcanization accelerators, pharmaceuticals. As emulsifying agent for cosmetic creams and lotions, mineral oil and paraffin wax emulsions, leather dressings, textile specialties, polishes, cleaning Compounds, so-called soluble oils. Absorbent for acidic gases. Biological buffer.
