blue dextran

The electrophoresis pattern of blue dextran and bromophenol blue supports it is the evaporation of water on cellulose surface to drive buffer to flow and to alter the electrophoresis of serum proteins.

兰色葡聚糖和溴酚兰在对应条件下电泳表明，主要是薄膜表面溶剂蒸发，造成缓冲液由两端朝中部补充而流动，从而改变了部分低荷质比血清蛋白的电泳行为。

A simple, rapid and reproducible method has been developed for the production of highly purified T4 DNA ligase in good yield from induced lysogens of λ T4 lig phages. Heparin-sepharose 4B and blue dextran-sepharose 4B affinity chromatographic columns were used to purify the enzyme.

我们采用简便、快速、重复性好的肝素-琼脂糖和蓝色葡聚糖-琼脂糖柱两次亲和层析方法，纯化得到了高纯度的T4-DNA连接酶。
