Association of CK2α/α’ with amyloid deposits in AD. Representative pictures are shown of combined Congo red and immunohistochemical stainings for CK2α/α’ of the cortex of two AD cases (a: Braak stage V, Table 1C case #45; b + c: Braak stage V/VI, Table 1C case #44). a Association of astrocytes immunoreactive for CK2α/α’ with a Congo red positive amyloid plaque. b Astrocytes immunoreactive for CK2α/α’ associated with a Congo red positive blood vessel. c Association of CK2α/α’ immunoreactivity with a Congo red positive capillary. Immunohistochemical detection was performed using DAB (brown) and nuclei were stained with haematoxylin (blue). Scale bar A-C 100 μm
