Bis-ANS
Biological Activity
Fluorescent probe for nonpolar cavities in proteins. Used to detect Aβ fibre (Kd = ~80 nM); exhibits distinct fluorescent profiles for fibres and oligomers. Fluoresces in hydrophobic environments, negligible fluorescence in water solutions. Excitation\emission λ ~ 355\520 nm at pH 7.4.
