Methoxy-X04 is a fluorescent dye that crosses the blood-brain barrier and selectively binds to beta-pleated sheets found in dense core amyloid Aβ plaques. Methoxy-X04 retains in vitro binding affinity for amyloid b (Ab) fibrils (Ki= 26.8 nM). Methoxy-X04 is fluorescent and stains plaques, tangles, and cerebrovascular amyloid in postmortem sections of AD brain with good specificity[1][2].
Methoxy-X04 (5-10 mg/kg, i.p., once time) differentiates individual plaques in PS1/APP mice within 30 to 60 min[2].
