6-p-Toluidino-2-naphthalenesulfonic acid(AB275049)

MW 313.4 Da, Purity >98%. Environmentally sensitive fluorescent probe for the conformational state of proteins. Non-fluorescent in water, becoming fluorescent when bound to membranes (q.y. ~0.27) or proteins (q.y. ~0.72). The fluorescence is also enhanced by cyclodextrins, permitting a sensitive method for separating and analyzing cyclodextrins with capillary electrophoresis.
