A. A23009A_PURE_Tau_WB-1_082024
Whole brain lysates (15 µg total protein) from 5 days old (P5) or 31 days old (P31) rats were resolved on a 4-12% Bis-Tris gel, transferred to a PVDF membrane, and probed with Purified anti-Tau Phospho (Thr231) (clone A23009A) or Pan anti-Tau antibody. Proteins were visualized by chemiluminescence detection using HRP Goat anti-mouse IgG (Cat. No. 405306). Direct-Blot™ HRP anti-GAPDH (Cat. No. 607904) was used as a loading control. Western-Ready™ ECL Substrate Plus Kit (Cat. No. 426316) was used as a detection agent. Lane M: Molecular weight marker.

    IHC staining with Purified anti-Tau Phospho (Thr231) on formalin-fixed paraffin-embedded human Alzheimer’s Disease cortex tissue (panels A and B) or normal human cortex tissue (panels C and D) following antigen retrieval using Citrate Buffer (pH 6.0) (Cat. No. 420902). The tissue was incubated without (panels A and C) and with (panels B and D) Purified anti-Tau Phospho (Thr231) (clone A23009A) followed by incubation with Alexa Fluor® 647 Goat anti-mouse IgG (Cat. No. 405322). Nuclei were counterstained with DAPI (Cat. No. 422801). Images were captured with a 40X objective. Scale bar: 50 µm

Description

Paired helical filaments (PHFs) are the major building blocks of neurofibrillary lesions in Alzheimer's disease brains and are composed of hyperphosphorylated Tau protein. Predominantly expressed in axons, alternatively spliced forms of Tau comprise a family of microtubule-associated proteins that normally promote and stabilize the assembly of microtubules. PHF-Tau differs from normal Tau by its abnormal hyperphosphorylation, which results in decreased binding of Tau to microtubules. The decreased affinity of PHF-Tau for microtubules, coupled with reduced levels of normal Tau, destabilizes microtubules leading to an impairment of axonal transport, neuronal death and the aggregation of PHFs. Therefore, hyperphosphorylation of Tau is believed to be a key event in the pathogenesis of Alzheimer's disease.

Recommended Usage

Each lot of this antibody is quality control tested by western blotting. For western blotting, the suggested use of this reagent is 0.125 - 1.0 µg/mL. For immunohistochemistry on formalin-fixed paraffin-embedded tissue sections, a concentration range of 1.0 - 10.0 µg/mL is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

For use in immunohistochemistry on FFPE tissues (IHC-P), we recommend Citrate buffer (Cat. No. 420902) for antigen retrieval.
