NIAD-4
目录号 : KCM15514 CAS No. : 868592-56-7 纯度 : ≥98%
NIAD-4 is a fluorescent probe that crosses the blood-brain barrier to bind with high affinity to amyloid-β (Aβ) plaques (K = 10 nM). It displays excitation/emission spectra of 475/625 nm, respectively, with the far-red emission occurring upon binding to Aβ.

生物活性

NIAD-4 is a blood-brain barrier permeable fluorophore for optical imaging of amyloid-β (Aβ) in the central nervous system (CNS) for Alzheimer’s disease (AD). NIAD-4 binds to the same Aβ site with the binding affinity (Ki) of 10 nM.

体外研究

NIAD-4 can bind to amyloid protein aggregates, hindering their internal rotation and increasing fluorescence yield and intensity, making it an effective tool for detecting amyloid protein. NIAD-4 can cross the brain barrier and, due to its neutral charge and low molecular weight, can be used for imaging amyloid fibrils in the brain. The excitation wavelength of NIAD-4 is 475 nM, and the emission wavelength is 610 nM.
