Aβ42 concentration in the CP epithelium with age. (A) Semi-quantitative IHC for Aβ42 deposition. Mean staining intensity in grayscale units (GU) was significantly decreased (p < 0.05) for the age groups, n = 5 per age group. (B) IHC of Aβ42 at 3 mo (left), 20 mo (center), and 36 mo (right) old rats. Staining is granular and primarily cytosolic (asterisks), though also found along the apical membrane (arrows).
