B) A serial section from the same HuVV mouse immunolabeled for PrP by using monoclonal antibody (Purified [3F4], Cambridge Bioscience, Cambridge, UK). C) Immunohistochemical staining for GFAP in the hippocampus of a HuVV mouse showing plaque-like deposits. No reactive astrocytosis is seen in the vicinity of plaques. D) A serial section from the same HuVV mouse immunolabeled for PrP by using monoclonal antibody 3F4. GFAP, glial fibrillary acid protein; HuVV, transgenic mouse expressing human PrP gene sequence coding for the valine-homozygous codon 129 genotype; PrP, prion protein. Scale bars indicate 50 μm.
