Tau-381 (1N3R) Wild-Type Pre-formed Fibrils

Human Recombinant Tau-381 (1N3R) Wild-Type PFFs

Product Specifications

Background

Several tau isoforms, including 1N3R, are expressed in the human brain, and the existence of multiple human tauopathies with distinct fibril morphologies suggests different molecular conformers incorporating different isoforms may exist (1, 2) . NMR data indicates that both 3R and 4R tau are incorporated into AD-tau seeded fibrils (3) .
