摘要: 搭建了一个纳升级的二维液相色谱分离平台(nano-2D-LC),该平台可以自动完成进样、除盐、分离及鉴定。以离子交换色谱(SCX)为第一维,反相液相色谱(RPLC)为第二维,对鼠肝组织的蛋白质组进行了研究。SCX采用阶梯式洗脱,RPLC运用线性梯度洗脱,以200 nL/min的速度进行分离,峰容量可达620。

Abstract: A nano flow comprehensive multidimensional liquid chromatography was developed. By using this separation platform, complex samples can be injected, desalted, separated and analyzed in complete automatization. Coupling of the strong cation-exchange (SCX) with capillary reversed-phase liquid chromatography (cRPLC) is described for proteomics of rat liver. A step gradient was applied for SCX column, and a linear gradient was applied for RPLC. The flow rate through the nano scale analytical column during the separation process was maintained at 200 nL/min. The peak capacity for the nano-2D-LC was up to 620 under these conditions.
