Alzheimer’s disease (AD) is a progressive neurological disorder characterized by the presence of amyloid-beta (Aβ) plagues and neurofibrillary tangles. The accumulation of Aβ plaques is an early event in the pathogenesis of AD. In AD research, there has been a growing need for in vivo Aβ imaging by two-photon microscopy, which enables deep-brain-fluorescence imaging. BioTracker PyrPeg Amyloid-b Live Cell Dye is a two-photon fluorescent probe that specifically detects insoluble Aβ, rather than tau and alpha-synuclein aggregates (1). This probe may serve as a useful blood-brain-barrier penetrating tool for optical and functional monitoring of insoluble forms of Aβ aggregates in the AD model brain (1).Reference:1.
