    • Vibratome sections (40 μm) of the brain of transgenic mice overexpressing human APP (amyloid precursor protein) were incubated for 1 h at room temperature with the non-radioactive compound 2 at a concentration of 1 μM. After incubation, the sections were rinsed with tap water and treated with 0.2% NaOH in 80% ethanol to reduce background staining. The slices were rinsed again with tap water and coverslipped using a Mowiol-DABCO solution. For immunohistochemical staining, the same vibratome sections were treated with a 0.1% Triton X-100 solution in PBS (PBST) and 10% foetal calf serum to block non-specific binding. The slices were subsequently incubated overnight with the amyloid-binding monoclonal antibody AβN25 (Oncogene Research Products, San Diego, CA, USA) which stains both dense and fibrillar plaques. The sections were treated again with PBST and rinsed with PBS before fixation with Mowiol-DABCO solution. Fluorescence microscopy was performed using a Leica DMR microscope equipped with a digital Leica DC480 camera and a UV filter set with following specifications: excitation: 340-380 nm bandpass filter, dichromatic mirror 400 nm; emission: 425 nm longpass filter. The images were collected and processed with Leica IM500 image processing software.

    • ® (fentanyl citrate 63 μg/ml and fluanisone 2 mg/ml). The mice were sacrificed by decapitation at 2 or 60 min pi. Blood was collected in a tared tube and weighed. All organs and other body parts were dissected and weighed, and their radioactivity was counted in a gamma counter. Results were corrected for background radioactivity and are expressed as percentage of the injected dose (% ID) or as percentage of the injected dose per gram tissue (% ID/g). For calculation of total radioactivity in blood, blood mass was assumed to be 7% of the total body mass.
