Udi等人提出了一种新的方法,可以在保持细胞核完整性的同时对多种哺乳动物细胞进行定量亚细胞分离。该方法为不同细胞区室的质谱分析和德都维富集分析提供了一种快速可靠的方法。亚细胞分离与基于质谱的蛋白质组学相结合是研究健康和疾病中关键蛋白质定位的有力工具。在这里,我们提供了一种可靠和快速的方法,哺乳动物细胞分离,调整这种蛋白质组学分析。这种方法被证明很容易适用于不同的细胞系,在这些细胞系中,所有的细胞内容物都被考虑在内,同时保持细胞核和核膜的完整性。我们通过量化核输出抑制剂对核质和细胞质蛋白质组的影响来证明该方法的实用性。
Udi et al. present a new method for quantitative subcellular fractionation of a wide range of mammalian cells while maintaining nuclear integrity. This method provides a fast and reliable means to perform mass spectrometry and DeDuvian enrichment analyses for the different cellular compartments. Subcellular fractionation in combination with mass spectrometry–based proteomics is a powerful tool to study localization of key proteins in health and disease. Here we offered a reliable and rapid method for mammalian cell fractionation, tuned for such proteomic analyses. This method proves readily applicable to different cell lines in which all the cellular contents are accounted for, while maintaining nuclear and nuclear envelope integrity. We demonstrated the method’s utility by quantifying the effects of a nuclear export inhibitor on nucleoplasmic and cytoplasmic proteomes.
