To address this question, we first applied the oligomers directly after the purification of the protein eluting from the Butyl FF 16/ 10 column (without buffer exchange; 1, 5, and 10 mM) to SHSY5Y cells and observed a variety of toxic effects, including pronounced reduction in the cell viability (by MTT assay, Fig. 3A), increase in apoptotic cells (by Hoechst staining, Supplementary Fig. 4A), loss of mitochondrial membrane potential (by JC1 assay, Supplementary Fig. 4B), caspase 3/7 activation (Supplementary Fig. 4C-D), and cytochrome-c release (Supplementary Fig. 4), within 5 hours of incubation.

In our hands, these aggregated tau species formed in different conditions did not show any significant release of LDH when applied on the differentiated SH-SY5Y cells (Supplementary Fig. 8A), and they did not show a significant reduction in cell viability by the MTTassay (Supplementary Fig. 8B).
