Capillary isoelectric focusing (CIEF) is a more rapid technique for separating proteins that the traditional gel-based technique.

和传统的凝胶技术相比，毛细管等电聚焦(CIEF)是一种蛋白质的快速分离技术。

Proteins were separated and resolved in CIEF according to their differences in isoelectric point (pI), and then characterized by ESI MS.

蛋白质首先在毛细管等电聚焦过程中根据它们等电点的差异得到分离，然后被电喷雾质谱鉴定。
