Size: 1mg

5-10 business days

QM-FN-SO3 is small-molecule fluorescent probe designed for directly mapping of amyloid-?(A?) plaques in vivo. It exhibited extraordinary features of ultra-high S/N ratio, remarkable binding affinity with BBB penetrability, and high-performance near-infrared emission. The detection characteristics of QM-FN-SO3 greatly streamline and improve the protocols for A? analysis in living animals. QM-FN-SO3 serves as a promising alternative to commercial probes such as Thioflavin derivatives (ThT or ThS) for Alzheimer’s disease (AD) research. Excitation maximum = 500 nm; emission maximum = 670 nm.
