Descripción

Application

Trizma is used in the formulation of buffer solutions in the pH range between 7.5 and 8.5. Tris buffer solutions are widely used in cell and molecular biology for processes such as protein and nucleic acid extraction and purification. Trizma based buffers are also in column chromatography and in gel electrophoresis. Trizma hydrochloride is used as a general reagent for the preparation of all types of Tris buffers.

Other Notes

Los valores de pH de todas las disoluciones tampón son dependientes de la temperatura y la concentración. En el caso de los tampones Tris, el pH aumenta alrededor de 0,03 unidades por cada °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.

Component of extraction buffer e.g. phenol extraction of DNA or RNA; Buffer component of separating and stacking gels in the characterization of in vitro translation products by SDS-PAGE.
