The gold standard for Sterol Lipids Analysis is a combination of chromatography and mass spectrometry (LC-MS/MS or GC-MS/MS). Chromatography (LC or GC): This first step acts like a molecular sorting system, separating the different sterol lipids from each other and from other molecules in the ...
The workflow typically involves high-resolution mass spectrometry (LC-MS/MS) coupled with sophisticated enrichment strategies. First, proteins are extracted from cells or tissues and digested into smaller peptides. ...
Using specialized tools like antibodies that recognize the unique signature left after ubiquitin digestion (the "di-glycine remnant" or K-GG motif), scientists can selectively isolate ubiquitinated peptides from a cell lysate. Mass Spectrometry (LC-MS/MS): This enriched sample is then analyzed by liquid chromatography-tandem mass spectrometry ...
