Vue d’ensemble

A far-red (near-infrared) fluorescent contrast agent that permeates the blood-brain barrier (BBB) ​​for highly specific in situ and in vivo staining of amyloid plaques.
NIAD-4 is a far-red (near-infrared) fluorescent contrast agent that permeates the blood-brain barrier (BBB) ​​for highly specific in situ staining of amyloid plaques (10 μM in DMSO/propylene glycol solution; coronal sections of APP mice) and in vivo staining (2 mg/kg intravenous injection in APP mice). Due to its push-pull design and significantly enhanced affinity for the thioflavin T (ThT) site (Ki = 10 nM/NIAD-4 vs 580 nM/ThT), NIAD-4 exhibits a significant red-shift in absorbance (~70 nm) and a 1.3-fold increase in extinction coefficient upon binding to aggregated amyloid-β 1-40 (4.1 μM NIAD-4 and 10 μM amyloid-β in PBS). Excitation light 450-488 nm, emission light 550-650 nm.
