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

Trizma^® base was used as buffer for the following studies:

• Electrophoretic transfer for the specific identification of isozymes of starch debranching enzyme, α-amylase and 9-amylase.[1]
• Electrophoretic separation of lipoproteins in polyacrylamide gels.[2]
• Preparation of TRIS buffer having pH 8.[3]

It may be used to compose DN buffer for DNA nick-end labeling of tissue sections.[4]

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.
