Carbohydrate characteristics of EP granules vs PAS granules. A-D Effect of the preadsorption of IgM antibodies with a 0.4 M sugar mixture in the IgM staining (red) of EP granules from the fissures (zone 2, A and B) and in PAS granules from the hippocampus (C and D). E–H Effect of the pre-treatment with 200 U/mL of γ-amylase on the staining with IgM in EP granules (zone 2, E and F) and in PAS granules from the hippocampus (G and H). I-L Effect of a 40 min boiling pre-treatment on the staining with IgM in EP granules (zone 2, I and J) and in PAS granules from the hippocampus (K and L). Scale bars: 100 µm
