Figure 1From: Polysialic acid is associated with better prognosis and IDH1-mutation in diffusely infiltrating astrocytomas Staining patterns of polysialic acid and NCAM. A positive expression of polysialic acid detected with EndoNA2-GFP fusion protein is shown in figure A, and positive NCAM expression in figure B in glioblastoma. Overlay image of A and B showing the colocalized expression of polysialic acid and NCAM in same tumor sample (C). Negative staining of polysialic acid (D), positive staining for NCAM (E), and overlay image of D and E (F) in pilocytic atrocytoma. Scale bar, 40 μm.Back to article page
