Florbetaben F18 is a18F-labeled stilbene derivative used as a tracer for PET imaging of beta-amyloid deposits in the human brain. The F 18 isotope produces a positron signal that is detected by a PET scanner. 3H-florbetaben in vitro binding experiments reveal two binding sites (Kd of 16 nM and 135 nM) in frontal cortex homogenates from patients with AD. Binding of florbetaben F18 to beta-amyloid plaques in post-mortem brain sections from patients with AD using autoradiography correlates with both immunohistochemical and Bielschowsky silver stains. Florbetaben F 18 does not bind to tau or alpha-synuclein in tissue from patients with AD. Neither Neuraceq nor non-radioactive florbetaben F 19 bind to AT8 positive tau deposits in brain tissue from patients with frontotemporal dementia (FTD), using autoradiography and immunohistochemistry, respectively.

Sample Use Guides

In Vivo Use Guide

The recommended dose is 300 MBq (8.1 mCi), maximum 30 mcg mass dose, administered as a single slow intravenous bolus (6 sec/mL) in a total volume of up to 10 mL.

Route of Administration: Intravenous

In Vitro Use Guide

Fresh-frozen and paraffin-embedded tissue from AD, FTLD-tau and DLB patients and age-matched non-demented controls were used for autoradiographic analysis. Frozen sections, sliced at a 18-μm thickness on a cryostate, and paraffin sections, sliced on a sliding microtome at a thickness of 6μm, were mounted onto glass slides. Paraffin sections were deparaffinized using routine histological methods before performing binding studies and immunohistochemistry, respectively. For autoradiography, sections were incubated with 10 Bq/μl [18F]-florbetaben (specific activity, 351 Ci/mmol) diluted in 25 mM HEPES buffer, pH 7.4, and 0.1% bovine serum albumin (BSA) (200μl/slide) for 1 h at room temperature (RT) in a humidified chamber. Autoradiographic signals were detected by a phosphoimager device (Fuji BAS5000).
