TRIS 99.9% Biochemical Grade

Synonym(s): 2-Amino-2-(hydroxymethyl)-1,3-propanediol, THAM, Tris base, Tris(hydroxymethyl)aminomethane, Trometamol

Description

Tris buffer is not only widely used as a solvent for nucleic acids and proteins, but also has many other important applications. Tris is used for protein crystal growth under different pH conditions. [3] The low ionic strength characteristic of Tris buffer can be applied to the formation of intermediate filaments of lamin (a nuclear lamina protein) in C. elegans. [4] Tris is also one of the main components of protein electrophoresis buffers. In addition, Tris is an intermediate in the preparation of surfactants, vulcanization accelerators, and some drugs. Tris is also used as a titration standard.

Specifications

Features

• Ultra-high purity (≥99.9%) biochemical grade ensuring consistent performance in sensitive molecular biology, biochemistry, and analytical applications.

• Strong and stable buffering capacity with a pKa near 8.1 at 25 °C, providing reliable pH control within the biologically relevant range (pH 7.0–9.0).

• Excellent solubility and easy preparation, allowing quick dissolution in water and straightforward pH adjustment using HCl or base.

• Low ionic strength and biomolecule-compatible, minimizing interference with nucleic acids and proteins and supporting structural integrity in various assays.

• Broad chemical versatility, serving not only as a core laboratory buffer component but also as an intermediate in the synthesis of surfactants, vulcanization accelerators, and pharmaceutical-related chemicals.

• High stability and low impurity profile, featuring extremely low heavy metals, minimal insoluble matter, and reduced UV absorbance for cleaner biochemical reactions.

Applications

• Nucleic acid and protein buffers

  Widely used as a primary buffering component in DNA/RNA extraction buffers, protein solubilization solutions, sample storage buffers, and general molecular biology reagents.

• Electrophoresis and blotting

  A key component of commonly used electrophoresis systems such as Tris-Glycine, Tris-HCl, TAE, and TBE buffers, providing stable pH and consistent migration for both nucleic acids and proteins.

• Protein crystallization and structural biology

  Suitable for protein crystal growth across a broad pH range, offering stable chemical conditions for structural studies and biophysical assays.

• Cell culture and biochemical reactions

  Maintains near-physiological pH in enzyme assays, metabolic studies, cell-free systems, and other biochemical workflows requiring gentle buffering conditions.

• Analytical chemistry and titration

  Frequently used as a titration standard due to its well-defined purity and stable acid–base characteristics.

• Chemical and industrial synthesis

  Functions as an intermediate or precursor in the production of surfactants, rubber vulcanization additives, and certain pharmaceutical intermediates.
