Description

FSB is a fluorescent probe that has been used for the detection of amyloid plaques in human postmortem brain from patients with Alzheimer’s disease and of curli amyloid fibers in E. coli biofilms. It has also been used to label tau inclusions in mouse and human brain sections and in mouse spinal cord following intravenous injection. FSB has excitation/emission maxima of 390/520 nm, respectively.
