Imaging mass spectrometry (IMS) is a novel quantitative technique used to investigative diverse biomolecules in tissue sections. Specifically, IMS uses analytical separation of mass spectrometry to determine the spatial distribution of certain lipids and/or proteins located directly on biological sections from a single tissue sample. Typically, IMS is(More)
The resolution of MALDI MS imaging is limited by the displacement of analytes during matrix deposition or by laser focal diameter. Here we present three methods that minimize the displacement of analytes during matrix deposition, including a method where image resolution is not limited by the laser focal diameter. The first method, matrix solution fixation,(More)
