h-FTAA is a luminescent conjugated oligothiophene (LCO) probe. h-FTAA can selectively bind to amyloid protein aggregates (such as Aβ plaques) and distinguish different conformations of the protein aggregates through changes in fluorescence signals. h-FTAA significantly reduces the neurotoxicity of Aβ1-42 and the Arctic mutant Aβ (AβArc), thereby protecting SH-SY5Y neuroblastoma cells. h-FTAA can be used to dynamically track the formation and maturation process of Aβ plaques [1] [2].
