Tau-441 (2N4R) Wild-Type Oligomers

Human Recombinant Tau-441 (2N4R) Wild-Type Oligomers (Baculovirus/Sf9)

Product Specifications

Background

Tau (tubulin-associated unit) is normally located in the axons of neurons where it stabilizes microtubules. Tauopathies such as Alzheimer’s Disease (AD) are characterized by neurofibrillary tangles containing hyper-phosphorylated tau fibrils (1) with consensus that tau oligomers are the most toxic species initiating neurodegeneration (2) . Hyper-phosphorylated tau can be generated via expression in the Sf9/Baculovirus system, with up to 20 sites confirmed by mass spectrometry and western blots with phospho-specific antibodies (3) . Our Sf9/Baculovirus-expressed Tau 2N4R oligomers are formed without the use of heparin or another anionic scaffold.
