无色液体,0.22μm膜过滤纯化。组分为1M Tris碱;pH 6.8,25℃。pH值因温度而异,请在室温使用。一般来说,温度每上升1℃,pH值下降0.03。如果低温保存缓冲液,可能会产生沉淀,可摇晃或加热溶解;实验室最常用的一种缓冲液,可以用于各种常规生化、分子生物学实验
General description
Colorless liquid, purified by filtration through a 0.22 μm membrane. The composition is 1 M Tris base; pH 6.8, 25°C. pH varies with temperature; please use at room temperature. Generally, the pH decreases by 0.03 for every 1°C increase in temperature. Precipitation may occur if the buffer is stored at low temperatures; it can be dissolved by shaking or heating. This is one of the most commonly used buffer solutions in the laboratory and can be used for various routine biochemical and molecular biology experiments.
