Hence, treatment must be taken inside the interpretation of your alanine scan outcomes regarding the constructions of the input seeds. Potential cryo-EM construction willpower of your seeded aggregates, perhaps without their fluorescent labels, would resolve these uncertainties, and would insert valuable data to answer the problem what establishes the development of distinct tau folds in the various ailments.
