• in gas chromatography/mass spectrometry (GC/MS)-based sterol profiling to quantify 7-dehydrocholesterol in oligodendrocyte progenitor cells (OPCs)
• as an internal standard for the analysis of sterols and oxysterols using ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS)
• as an internal standard for lipid measurements by liquid chromatography (LC)-MS

生化/生理作用
