Bioactivity-ELISA
 Tau ELISA

Immobilized Human Tau-441 GSK-3beta-phosphorylated protein, His Tag (Cat. No. TAU-H5147) at 1 μg/mL (100 μL/well) can bind Anti-Phospho-Tau (Thr181) Monoclonal Antibody, Mouse IgG with a linear range of 1-31 ng/mL (QC tested).

 Tau ELISA

Immobilized Human Tau-441 GSK-3beta-phosphorylated protein, His Tag (Cat. No. TAU-H5147) at 1 μg/mL (100 μL/well) can bind Anti-Tau Antibody with a linear range of 0.1-8 ng/mL (Routinely tested).

Mass Spectrometry
 Tau MASS_SPECTROMETRY

Mass spectrometry reveals 8 phosphorylation sites on E.coli expressed Human Tau-441 GSK-3beta-phosphorylated protein, His Tag (Cat. No. TAU-H5147) as shown on the modified phosphorylation PTM spectrum. The protein sequence coverage was 40% (Routinely tested).

Western Blot
 Tau WESTERN BLOT

Western blot was performed by loading Human Tau-441 GSK-3beta-phosphorylated protein, His Tag (Cat. No. TAU-H5147): 400ng, and it was electrophoresed using NuPAGE™ 12% Bis-Tris Protein Gel. Human Tau 441 GSK-3beta-phosphorylated protein, His Tag (Cat. No. TAU-H5147) were transferred onto a pvdf membrane by Tanon Trans-Blot. Anti-Phospho-Tau (Thr181) Monoclonal Antibody is primary antibody (1 μg/mL) and (MFC) Peroxidase Affini Pure Goat Anti-Mouse IgG, Fcγ Fragment Specific (minXHu, Bov, HrSrProt (1:1500)) is second antibody detected by chemiluminescence with using the iBright 1500 (Chemiluminescent detection was performed using BeyoECL Plus).

  • Background
    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.
