The assay used a recombinant fragment of the protein tau, called K18, with a specific mutation, to identify inhibitors of tau aggregation. The assay monitored fibrillization using Thioflavin T (ThT) fluorescence. Tau is important for stabilizing microtubules in neurons and contributes to important cellular functions, but can lead to neuronal loss and dysfunction when aggregated into neurofibrillary tangles. Is the molecule effective to this assay?
