Plant Subcellular Compartments Untargeted Lipidomics
- Mass spectrometric-based lipidomics methods in recent years have revealed considerable complexity of lipid composition within organisms and tissues providing a wealth of information related to lipid metabolism and signaling；
- Although quite sensitive, these profiling methods rely on conventional tissue extractions of total lipids which results in a loss of original cellular context of lipid metabolites. The spatial distribution of lipids in cells is certain to be as important to their functions as their changes in concentrations;
Creative Proteomics has focused on developing approaches for high resolution sampling of lipids in plant subcellular compartments. We used direct organelle mass spectrometry (DOMS) that profiles lipids at the organelle level.
- Direct Organelle Mass Spectrometry (DOMS)
- DOMS involves sampling organelles on a microscope stage using nano‐electrospray capillary tips
- The lipids are extracted from organelles within the capillary tip by microphase extraction, and identified and quantified by direct‐infusion nanospray MS.
Creative Proteomics has rich experience in plant subcellular compartments untargeted lipidomics, from the commonly used model plant arabidopsis to the main food crops rice, wheat and soybeans. We routinely cover a rich variety of sample types, including lipid droplets (LDs), chloroplasts, mitochondria, plasma membranes, endoplasmic reticulum.
