    Thioflavin T emission curves show increased fluorescence (correlated to tau aggregation) over time in active tau monomers (SPR-327). A greater increase in fluorescence is seen when 50 μM active monomer (SPR-327) is combined with 10 μM of active fibrils (SPR-329 or SPR-330), as the active fibrils seed the formation of new fibrils from the pool of active monomers.
