Comparison of MALDI MSI data acquired from liver samples embedded in 5% gelatin, 2% agarose, and non-embedded samples. (A) Fractional mass plots of the mean mass spectra acquired from the 5% gelatin, 2% agarose embedded samples, and from the non-embedded samples. (B,C) show the distributions of two lipid ions, assigned to proton adducts of PC(36:2)/PE(39:2) and SM(34:1)/PE-Cer(37:1).
