Comprehensive LC–MS2 workflows enable precise BMP species profiling by distinguishing BMPs from phosphatidylglycerol using retention time and positive-mode MS2 fragmentation, including in CLN5 knockout cells.
- Why it matters: BMP dysregulation is linked to disorders such as neurodegenerative diseases, but BMP identification is difficult because BMPs closely resemble phosphatidylglycerol isomers.
- What they did: The study developed LC–tandem mass spectrometry methods for an untargeted Orbitrap and a targeted triple quadrupole, using hydrophobicity and MS2 fragmentation to annotate BMPs versus PGs. It also leveraged CLN5 knockout versus wild-type lipid extracts to confirm BMP depletion when MS2 coverage is incomplete.
- The result: Lipid extraction and preparation take ~4 h, with unattended LC–MS instrument time scaling by sample number and ~1 d for computer-based data analysis, enabling robust BMP profiling and annotation for health and disease research.
