Figure Lengend Snippet: Tissue imaging of mouse brain sections and an exogenous lipid spotted on rat brain section in positive ion mode. ( A ) Average mass spectra and the corresponding ion images obtained from three adjacent tissue sections using three different aspiration capillaries, respectively, in a high mass resolution mode with a mass resolution of 200,000 (at m/z 400) and a spatial resolution of 150 μm. ( B ) Optical image and MSI result of different amounts (from 2.6 pmol to 80.4 pmol) of [PC(24:0)+K] + ( m/z 600.4001) spotted (1 μL) on a rat brain tissue section. ( C ) Standard curve by plotting the amounts of each spot against the average intensities of m/z 600.4001 each spot. Error bars represent the standard deviation of the intensity of m/z 600.4001 from about 130 mass spectra in each spot.
Article Snippet: PC(24:0) and PC(36:0) were purchased from Avanti Polar lipids (Alabaster, AL).
