PHF-6_PURE_Tau-Phospho-Thr231_Antibody_1_032123
Rat brain whole tissue lysates (15 µg total protein) from 31 days (negative control) and 5 days post-partum animals (positive control) were resolved on a 4-12% Bis-Tris gel, transferred to a PVDF membrane, and probed with 1.0 µg/mL of purified anti-Tau phospho (Thr231) (clone PHF-6) for 2 hours at room temperature. Proteins were visualized by chemiluminescence detection using HRP Goat anti-mouse IgG (Cat. No. 405306) at a 1:3000 dilution. Direct-Blot™ HRP anti-GAPDH (Cat. No. 649204) was used as a loading control at a 1:50000 dilution. Western-Ready™ ECL Substrate Premium Kit (Cat. No. 426319) was used as a detection agent. Lane M: Molecular weight marker

    IHC staining of purified anti-Tau Phospho (Thr231) (clone PHF-6) on formalin-fixed paraffin-embedded human Alzheimer's brain tissue. Following antigen retrieval using 88% formic acid, the tissue was blocked and incubated without (Panels A and C) and with (Panels B and D) Lambda Phosphatase Protein overnight at 4°C. The tissue was then incubated without (panels A and B) or with (panel C and D) 5 µg/mL of purified anti-Tau Phospho (Thr231) (clone PHF-6) overnight at 4°C. BioLegend’s Ultra Streptavidin HRP Kit (Multi-Species, DAB) (Cat. No. 929501) was used for detection followed by hematoxylin counterstaining, according to the protocol provided. Images were captured with a 40X objective. Scale bar: 50 µm

    Biotinylated Tau phospho (Thr231) (red line) or non-phospho (blue line) peptides were incubated at 2 µg/mL onto 96-well plates coated with NeutrAvidin in 0.1% BSA-PBST overnight at 4°C. Direct ELISA was performed by further incubating the plate with serial dilutions of purified anti-Tau phospho (Thr231) (clone PHF-6) in 0.1% BSA-PBST for 1 hour at room temperature. Bound antibody was detected with HRP Goat anti-mouse IgG (Cat. No. 405306). TMB substrate set (Cat. No. 421101) was used as a detection system. Absorbance was measured at 450 nm.

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.

Application

WB - Quality tested
IHC-P - Verified
Recommended Usage

Each lot of this antibody is quality control tested by western blotting. For western blotting, the suggested use of this reagent is 0.5 - 1.0 µg/mL. For immunohistochemistry on formalin-fixed paraffin-embedded tissue sections, a concentration range of 2.5 - 5.0 µg/mL is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

This antibody is effective in immunoblotting (WB).

The PHF-6 antibody reacts with human tau phosphorylated at Thr 231.

Direct ELISA was done using phospho and non-phospho specific peptides, mainly to confirm specificity. Application has not been verified on tissue/cell lysates.
