不相关的代谢组学研究提供了一个假说,产生一种代谢轮廓的快照。此协议将展示从细胞,血清或组织中的代谢产物的提取和分析。代谢物甲范围进行调查,采用液 - 液固相萃取,微流超高效液相色谱/高分辨率质谱(UPLC-HRMS)耦合到差分分析软件。

以下实验的总体目标是比较不同生物样品组的代谢概况快照。这是通过使用液体萃取来分离有机分子和极性分子来实现的。作为第二步,通过液相色谱法进一步分离分子,并通过高分辨率质谱法进行分析,从而提供保留时间、质荷比和强度数据以供进一步分析。

接下来,对液相色谱运行进行对齐,并对特征进行检测、定量和分选。为了识别组间差异丰富的特征。结果显示,根据液相色谱、高分辨率质谱法检测到的分析物丰度差异,不同处理条件的特征存在差异。
