Peptide mapping of MODE K derived epithelial exosomes using matrix assisted laser desorption ionisation-time of flight-mass spectrometry (MALDI-TOF-MS) analysis

Band NoProteins identified from MODE K derived exosomesMolecular mass (kDa)Proteins identified from MODE K+IFN-γ derived exosomesMolecular mass (kDa)
MODE K derived exosomes (20 µg) were run on 10% sodium dodecyl sulphate-polyacrylamide gel electrophoresis and stained with Coomassie blue. The major bands were excised from the gel and in-gel digested with trypsin. The digest solution was analysed by MALDI-TOF-MS.
IFN-γ, interferon γ.
