Flutemetamol F 18 binds to β-amyloid plaques in the brain and the F-18 isotope produces a positron signal that is detected by a PET scanner. In in vitro binding studies using postmortem human brain homogenates containing fibrillar β-amyloid, the dissociation constant (Kd) for flutemetamol was 6.7 nM.
Selectivity of [3H]flutemetamol binding in post-mortem human brain sections was demonstrated using autoradiography, silver-stained protein, and
