应用
Tris HCl is a commonly used biological buffer. Tris/Tris HCl as a buffering system has a very broad usage in biological systems for biopharmaceutical manufacturing, cell culture, diagnostics and molecular biology. The pKa of Tris is 7.77 which corresponds closely to a physiological pH of 7.36.
Tris HCl is used as the conjugate buffer component with Tris/Tromethamine/Trizma in biopharmaceutical buffer formulations (both upstream and downstream applications), electrophoresis separations and diagnostic reagent formulations.
所有缓冲液的pH值都与温度和浓度有关。对于Tris缓冲液，降温每℃其pH值约增加0.03单位，每10倍稀释其pH降低0.03-0.05单位。
对于精确的应用，请使用带有玻璃/甘汞组合电极并仔细校准过的pH计。
