WebMar 28, 2024 · Sarkosyl insoluble fibrillar tau is comprised of paired helical filaments seen by electron microscopy (EM), and is more resistant to proteinase K, compared to HMW tau which presents only sparse, short, filaments. Sarkosyl insoluble and HMW tau are nearly equivalent in potency in a HEK cell bioactivity assay for seeding aggregates. WebTau seeding 1. Introduction Tauopathies are a group of neurodegenerative diseases characterised by the pathological inclusions or aggregates of microtubule-associated tau protein in neurons and glial cells. Cytoplasmic inclusions in primary tauopathies predominantly comprise either three-repeat (3R) or four-repeat (4R) tau isoforms.
