TRIS (Trometamol, Tromethamine, Tris-[hydroxymethyl]aminomethane) Purity: 99.0-99.5% Buffering pH range 7.0-9.0 pKa at 25°C = 8.1 This grade of tris is excellent where purity and value are both important. It is superior to our technical grade tris and less expensive than our ultra pure material. This grade will suffice for most buffer applications.

Tris(hydroxymethyl)aminomethane (TRIS, Trometamol)

Supplier: MP Biomedicals

Tris has been useful as buffers in a wide variety of biological systems. Uses include pH control in vitro and in vivo for body fluids and in buffering systems for electrophoresis applications. Tris has been used as a starting material for polymers, oxazolones (with carboxylic acids) and oxazolidines (with aldehydes). Tris does not precipitate calcium salts and is of value in maintaining solubility of manganese salts. It can be used for the direct standardization of a strong acid solution; the equivalence point can be determined either potentiometrically or by use of a suitable indicator such as 3-(4-Dimethylamino-1-naphthylazo)-4-methoxybenzenesulfonic acid. It is an auxiliary material in pharmaceutical science.
Store at Room Temperature (15-30 °C). Store dessicated.

It is RNAse and DNAse-free. Tris is relatively non-hygroscopic ; but, if needed, it can be dried at 100 °C for up to 4 hours to remove any water.
Tris is used in pH control in vitro and in vivo for body fluids and in buffering systems for electrophoresis applications.Tris is used in assays used to characterize the activity and kinetics of the enzymes that catalyze SUMOylation of Small ubiquitin-like proteins (SUMO) and SUMO-dependent protein-protein interactions.
