Descripción

General description

Tris is an established basimetric standard and buffer used in biochemistry and molecular biology. It may be used by itself as a buffer or as a component of mixed buffer formulations, such as Tris-EDTA (TE) buffer, Tris-acetate-EDTA (TAE) buffer, Tris-borate-EDTA (TBE) buffer, etc. It is pure, essentially stable, relatively non-hygroscopic and has a high equivalent weight.

Application

Tris base has been used:

• As a component of lysis buffer for cell disruption
• In the preparation of TBE solution for PAGE (polyacrylamide gel electrophoresis)
• In studies of double stranded complexes of peptide nucleic acids (PNA) and their complementary DNA sequences, by use of anion exchange HPLC
• In capillary electrochromatography and UV analysis of tocopherols and tocotrienols

Packaging

Meets all specifications for T1503. For biotechnology, diagnostics or manufacturing use. Please inquire for commercial quantities.

Analysis Note

Not pyrogen tested. Certificates of analysis are available with lot specific information.

Other Notes

Los valores de pH de todas las disoluciones tampón son dependientes de la temperatura y la concentración. Para los tampones Tris, el pH aumenta alrededor de 0,03 unidades por °C de disminución de la temperatura, y disminuye 0,03-0,05 unidades al ser diluido por 10.
Para aplicaciones precisas, debe utilizarse un peachímetro cuidadosamente calibrado con un electrodo de vidrio/calomelano combinados.
