该协议结合毛细管电泳对蛋白质样品的特性进行了表征, 并对带电配体进行了快速结合筛选。推荐用于具有弹性结构的蛋白质, 如内在紊乱的蛋白质, 以确定不同构象的结合的差异。

该方法可以帮助回答有关内在无序蛋白质构造的关键问题,例如由于金属铁结合引起的构象变化。这种技术的主要优点是它需要的设备非常少,并且可以非常快速地获得结果。演示该程序的是我实验室的研究生 Matthias Stein。

首先,使用玻璃切割机上的玻璃切割机将带有聚酰胺外涂层和内径为 50 微米的裸熔融石英毛细管切割成 33 厘米和 30 厘米的长度。对于 CGE 实验,在距毛细管一端 24.5 厘米处,在 ACE 实验中,在距毛细管一端 21.5 厘米处,用笔在距毛细管一端 21.5 厘米处标记一厘米宽的检测窗口的中间。使用喷灯在每个标记前后 0.5 厘米处烧掉聚酰胺外部涂层。
