A summary of the MALDI workflow for both rapid diagnostics and tissue imaging. Final data (both tissue images and spectra) are actual experimental data from mouse liver. *Note that for formalin-fixed paraffin-embedded (FFPE) tissues other steps may be necessary including deparaffinization and antigen retrieval or direct application of trypsin digestion. MALDI, matrix assisted laser desorption imaging.
