WebJul 18, 2024 · MALDI is one of the most commonly used ionization methods linked to MSI as it provides a favorable balance between sample preparation, chemical sensitivity and spatial resolution ( 25 ). Now, with high-resolution MALDI-MSI, scientists can consistently detect hundreds of metabolites at a spatial resolution of <10 µm ( 26, 27 ).
WebN-glycan MALDI-2-MSI The current ‘gold standard’ method for N-glycan MALDI-MSI is based on the detection of alkali-metal adducts (predominantly sodiated species) in positive ion mode. Therefore, analysis of deprotonated species in (-)MALDI-2-MSI was compared to the ‘gold standard’ method to assess whether the same N-glycans would
WebMALDI-MSI was performed on fingerprints dusted with CFP and lifted with forensic lifting tape, demonstrating that more realistic samples can also be analyzed using MALDI-MSI.
