Relevance
Function: Tau promotes microtubule assembly and stability, and might be involved in the establishment and maintenance of neuronal polarity. The C-terminus binds axonal microtubules while the N-terminus binds neural plasma membrane components, suggesting that tau functions as a linker protein between both. Axonal polarity is predetermined by tau localization (in the neuronal cell) in the domain of the cell body defined by the centrosome. The short isoforms allow plasticity of the cytoskeleton whereas the longer isoforms may preferentially play a role in its stabilization. Tissue specificity: Expressed in neurons. Isoform PNS-tau is expressed in the peripheral nervous system while the others are expressed in the central nervous system. Involvement in disease: Polymerization of tau into insoluble aggregates within the CNS is a pathological hallmark of a clinically heterogeneous set of neurodegenerative diseases termed tauopathies, including Alzheimer disease (AD), corticobasal degenerations (CBD), progressive supranuclear palsy (PSP), and Pick’s disease (PiD). Tau isoforms are differentially incorporated into insoluble fibrillary structures in distinct tauopathies: for instance, in PSP and CBD 4R (microtubule binding repeat) isoforms are mostly incorporated in inclusion bodies, while in PiD 3R tau isoforms are predominant. Neuronal tau inclusions observed in AD consist primarily of both 3R and 4R isoforms, aggregated into hyperphosphorylated straight filaments (SF) and paired helical filaments (PHF). The resulting neurofibrillary tangles cause the loss of tau function of promoting assembly and stabilizing microtubules, and also the gain of a toxic function whereby the pathological tau sequesters normal tau, MAP1A/MAP1B and MAP2, and causes inhibition and disruption of microtubules. Sequence similarities: Four-repeat (type II) tau is expressed in an adult-specific manner and is not found in fetal brain, whereas three-repeat (type I) tau is found in both adult and fetal brain. Domain: The tau/MAP repeat binds to tubulin. Type I isoforms contain 3 repeats while type II isoforms contain 4 repeats. -

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Tau Alzheimer’s Disease antibody [GT-38] - Conformation-Specific (ab246808)
IHC image of Tau Alzheimer’s Disease staining in a section of formalin-fixed paraffin-embedded human Alzheimer brain performed on a Leica BONDTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab246808, 1ug/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset secondary-only control image is taken from an identical assay without primary antibody.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

GT-38 ELISA selectively detects AD-tau compared to tau monomer. GT-38 immobilized antibody selectively captures pathological tau derived from human AD brain tissue compared to recombinant tau monomer. GT-38 captured AD-tau antigens are detected with total tau rabbit polyclonal antibodies followed by HRP-conjugated anti-rabbit secondary and colorimetric readout. Total tau ELISA serves as a loading control demonstrating equivalent loading of total tau protein from both AD-tau and tau monomer.
Purified GT-38 mouse IgG1 antibody was coated on a 384 well plate at 450 ng/well (30 uL of 15 ng/uL) in 0.1 M NaHCO3 pH 9.6 at 4°C overnight. Plates were washed with PBST (phosphate buffered saline pH 7.2 with 0.05% Tween20) five times. GT-38 capture antibody was blocked with a commercial blocking solution 4°C overnight. Antigens consisted of either human brain derived insoluble tau enriched extract (AD-tau) or purified recombinant tau monomer. AD-tau was sonicated with a probe sonicator and antigens diluted in 0.2% BSA in PBS and applied to immobilized GT-38 and allowed to incubate 4°C overnight. Plates were washed with PBST five times. Rabbit polyclonal total tau detection antibody was diluted to 3.7 μg/mL in Buffer C (20 mM sodium phosphate pH 7.0, 2 mM EDTA, 400 mM sodium chloride, 1% BSA, 0.005% thimerosal), 30 μL was added to each well and incubated for 1 hour at room temperature. Plates were washed with PBST five times. Anti-rabbit HRP conjugated was diluted 1: 3,000 in Buffer C, 30 μL was added to each well and incubated for 1 hour at RT. Plates were washed with PBST five times. Colorimetric HRP substrate (30 μL/well) was added to the plate and developed at RT for 10 minutes. The reaction was quenched with addition of 30 μL/well 10% H2PO4 and the absorbance was measured at wavelength 450 nm.
