INTRODUCTION AND OBJECTIVE
Taking into consideration the challenges of lipid analytics, present study aims to design the best high-throughput workflow for detection and annotation of lipids.
MATERIAL AND METHODS
Serum lipid profiling was performed on CSH-C18 and EVO-C18 columns using UHPLC Q-TOF-MS and generated lipid features were annotated based on m/z and fragment ion using different software.
RESULT AND DISCUSSION
Better detection of features was observed in CSH-C18 than EVO-C18 with enhanced resolution except for Glycerolipids (triacylglycerols) and Sphingolipids (sphingomyelin).
CONCLUSION
The study revealed an optimized untargeted Lipidomics-workflow with comprehensive lipid profiling (CSH-C18 column) and confirmatory annotation (LipidBlast).
简介和目的
考虑到脂质分析的挑战，本研究旨在设计最佳的高通量工作流程，以检测和注释脂质。
材料和方法
使用 UHPLC Q-TOF-MS 在 CSH-C18 和 EVO-C18 柱上进行血清脂质分析，根据质荷比（m/z）和碎片离子使用不同的软件对生成的脂质特征进行注释。
结果与讨论
与 EVO-C18 相比，CSH-C18 柱对特征的检测更好，分辨率更高，但甘油酯（三酰基甘油）和鞘脂（神经酰胺）除外。
结论
该研究揭示了一种优化的非靶向脂质组学工作流程，具有全面的脂质分析（CSH-C18 柱）和确证性注释（LipidBlast）。
