Thioflavin T is a fluorescent dye that binds to beta sheet-rich structures, such as those in tau fibrils. Upon binding, the emission spectrum of the dye experiences a red-shift and increased fluorescence intensity. Thioflavin T emission curves show increased fluorescence (correlated to tau aggregation) over time in tau preformed fibrils (GTX17675-pro). Tau preformed fibrils (GTX17675-pro) seed the formation of new tau fibrils when combined with tau monomers (GTX17672-pro). Thioflavin T ex = 450 nm, em = 485 nm.
