Toperform MS imaging on these kinds of samples， Hamamatsu developed a large-sized DIUTHAME (60 mm X40 mm effective area). This papershows the MS imaging results of a large strawberry using the DIUTHAME blotting method， which does not require thin sectioning. Measurement conditions Measurement mode： Laser pitch 300 pm Positive ion， reflectron mode Sample： Fresh strawberry ("Skyberry" from Tochigi Prefecture)， 2L size (35 mm X 40 mm) Method 2 Cutting S etting To lay the strawberry flat， maketwo cuts with a knife. Place DIUTHAME on the cutsurface. Allow the DIUTHAME to soak upthe strawberry's components. After drying， attach the DIUTHAMEon an MTP TLC Adapter (Bruker)and perform MS imaging. Results Measurements were performed in collaboration with Associate Professor Hirofumi Enomoto，The Department of Biosciences， Teikyo University.
