Immunohistological analysis of mouse brains treated with PFCnD-induced BBB opening. Images are in coronal orientation and labeled by sectioning distance. Sections were stained with anti-IgG (green) and DAPI (blue). Localized IgG fluorescence was present on the treated (right) side of the brain. The untreated (left) side of the brain shows little to no IgG fluorescence
