| Application【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 acetate is used to make Tris acetic acid buffers that are used as diluents for various assays and as an electrophoresis running buffers. |
