The staining pattern of a primary neuroblastoma. A, expression of polySia-NCAM detected with the EndoNA2-GFP fusion protein. B, NCAM expression (stained with Alexa Fluor 594) of the same location. C, overlay image of A and B identifying colocalized expression of polySia-NCAM and NCAM. Scale bar, 40 μm.
