  • Molecular Characterization

    Tau Structure

    Other Tags and Version Biotin & Other Labeled Version

    This protein carries no "tag".

    The protein has a calculated MW of 45.8 kDa. The protein migrates as 40 kDa, 50 kDa and 55-63 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Supplied as 0.2 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5 with glycerol as protectant.

Background

p-Tau181 is a crucial blood-based biomarker for Alzheimer’s disease. It reflects tau pathology and amyloid-β burden, offering a non-invasive, accessible, and cost-effective tool for early detection, screening, and clinical management of cognitive impairment. Recombinant human tag-free Tau-441 was co-expressed with an active kinase in E. coli cells, followed by a proprietary treatment to selectively phosphorylate Thr181 while leaving Thr217 and Thr231 unphosphorylated.
