Thioflavin T, Fluorescent cell-permeable amyloid binding

Thioflavin T (ThT; 4-(3,6-dimethyl-1,3-benzothiazol-3-ium-2-yl)-N,N-dimethylaniline chloride), is a well-known fluorescence probe used for detecting amyloid fibrils . Upon binding to fibrils, ThT displays a dramatic shift of excitation maximum (from 385 to 450 nm) and emission maximum (from 445 to 492 nm) ( 22 , 23 ), resulting in an increase. Thioflavin T (ThT) was incorporated in amyloid fibers and displays an enhanced fluorescence (Ex 440nm/Em 480nm). ATP-Mg or nonhydrolysable APPCP-Mg prevented formation of amyloid fibers of Aß42 peptide (E) and the prion domain of the yeast Mot3 protein (Mot3-PrD) (F) in a concentration-dependent manner process was monitored via Thioflavin T (ThioT) fluorescence. Interestingly, sumoylation of -synuclein completely abolished fibril formation even after 146 h of incubation (Fig. 2, A-C). In contrast, the presence of equimolar amounts of nonconjugated SUMO did not prevent fibril formation (Fig. 2, A, B, and D) indicated by light scattering, thioflavin T fluorescence, and transmission electron microscopy analysis. Increased 1-anilinonaphthalene-8-sulfonate binding to the proteins was also observed, indicating exposure of hydrophobic surface area. Thus, pressure appears to induce a conformational state of lysozyme that aggregates readily upon.
