Single Cell Analysis by High-Resolution Atmospheric-Pressure MALDI MS Imaging
- 632 Downloads
Complementary to other imaging techniques, MALDI MS imaging provides label-free analysis and chemical specificity, covering a wide range of molecules that can be visualized simultaneously. Here, we highlight a protocol to visualize lipids from single cardiac cells using high-resolution atmospheric-pressure matrix-assisted laser desorption/ionization coupled to an orbital trapping mass analyzer.
