基于两相预柱的在线二维分离系统用于人肝组织中磷酸肽的规模化鉴定
Online Multidimensional Separation System Based on the Biphasic Trap Column for Large Scale Phosphorylation Analysis of Human Liver
摘要
Abstract
A fully automated online multidimensional separation system, which is based on a reversed phase-strong cation exchange(RP - SCX) biphasic trap column, was developed for the large scale phosphorylation analysis of human liver. Compared with the conventional online SCX - RP system and off - line mode, the biphasic column can reduce the sample loss and improve the detection sensitivity. This system was applied in the large scale phosphorylation analysis of human liver and a total of 3 082 unique phosphopeptides, including 3 056 unique phosphorylation sites corresponding to 1 332 phosphoproteins were identified under the FDR < 1% . The molecular function and motif analysis of phosphoproteins has revealed the important role of phosphorylation in the liver physiological functions.关键词
