产品说明

应用

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 maleate is used in the preparation of Tris maleate buffers with lower effective pH buffering capacity than Tris buffers. Tris maleate buffers may be used in various grow media, in tissue preparations and as a diluent or washing buffer.
