PE154
Based on 1 Customer Validation
PE154 is a fluorescent probe that binds to Aβ plaques, as well as a potent fluorescent inhibitor of AChE and BChE, with an IC50 of 280 pM against hAChE and 16 nM against hBChE. PE154 is applicable for histochemical detection of Aβ plaques in mouse and human brain tissues. PE154 can be used in research related to Alzheimer's disease.

PE154 reversibly binds to human acetylcholinesterase through active site cation-π stacking and interactions with the peripheral anionic site; its binding to human butyrylcholinesterase relies on active site cation-π stacking, with reduced effects on the peripheral site[2][3].
PE154 binds to the β-sheet structure of Aβ plaques independently of cholinesterase binding, exhibits enhanced fluorescence upon binding to cholinesterase, and can target Aβ deposits in the hippocampus when delivered via nanoparticle carriers[2][3].
PE154 (20 nM; 300 s) causes a significant increase in fluorescence intensity upon binding to purified recombinant human acetylcholinesterase and human butyrylcholinesterase, but this phenomenon is not observed when it binds to bovine serum albumin[3].

Animal Model:Triple-transgenic (TTG) (13-19 months old, harboring mutant human APPswe, PS-1, and tauP301L)[2]
-
Dosage:2 μL (0.1 mg/mL)
-
Administration:stereotaxic injection into dorsal hippocampus; single dose
-
Result:Fluorescently labelled Aβ-immunopositive senile plaques in the hippocampus as early as 4 hours post-injection, with labelling persisting for up to 7 days.
Labelled approximately 80% of Aβ-immunoreactive plaques in rostral hippocampal regions (including the subiculum) in both hemispheres.
Primarily targeted the core of Aβ plaques, not the outer rim.
Selectively bound Aβ and did not target hyperphosphorylated tau or reactive astrocytes surrounding plaques.
