应用
Tris(hydroxymethyl)aminomethane is used as a buffer in biochemistry and molecular biology laboratories. It is used as a primary standard to standardize acid solutions for chemical analysis. It finds application in cell membranes to increase permeability. As an alternative to sodium bicarbonate, it used in the treatment of metabolic acidosis. It acts as a precursor for the preparation of polymers, oxazolones and oxazolidines. Grade Specifications

产品说明 应用 Tromethamine is a commonly used biological buffer which is also referred to as Tris or Trizma. Tris as a buffer has very broad usage in diagnostics and downstream purifications. The pKa of Tris is 7.77 which corresponds closely to a physiological pH of 7.36.
Tromethamine is used in biopharmaceutical buffer formulations (both upstream and downstream), electrophoresis separations and diagnostic reagent formulations. Tromethamine is especially useful in downstream purification processes. 包装 Product is available in the following package sizes:
RES3193T-A701X: 100 gm container
RES3193T-A703X: 5 kg container
