    Thioflavin T emission curves show increased fluorescence (correlated to alpha synuclein aggregation) when A53T alpha synuclein Pre-formed fibrils (SPR-326) are combined with A53T alpha synuclein monomers (SPR-325). The Pre-formed fibrils seed the formation of new fibrils from a pool of monomers.Cisbio Total Alpha Synuclein AssayCisbio Alpha Synuclein Aggregation Assay

    SPR-327_Tau-Protein-Monomer-SDS-PAGE-1.png
    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.
