Human Tau-441 / 2N4R Protein, His Tag

Tau is a microtubule-associated protein, which encodes by the MAPT gene that located on chromosome 17q21. Tau Promotes microtubule assembly and stability, and might be involved in the establishment and maintenance of neuronal polarity. Hyperphosphorylation of the tau protein (tau inclusions, pTau) can result in the self-assembly of tangles of paired helical filaments and straight filaments, which are involved in the pathogenesis of Alzheimer's disease, frontotemporal dementia, and other tauopathies. Tau-441 is known as "2N4R, " "Isoform Tau-F, " "Tau-4" or "Tau 441", which consisting of 441 amino acid. Tau-441 is a potential therapeutic target for pathogenesis.

This protein carries a polyhistidine tag at the N-terminus. The protein has a calculated MW of 47.9 kDa. The protein migrates as 60 kDa under reducing (R) condition (SDS-PAGE) .

● -20°C to -70°C for 12 months in lyophilized state; ● -70°C for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Immobilized Human Tau-441, His Tag (Cat. No. TAU-H51H3) at 5 μg/mL (100 μL/well) can bind Tau Monoclonal Antibody with a linear range of 1-20 ng/mL (Routinely tested).
