SMI-51_Purified_Tau-95-108_Antibody_1_011019
Western blot of purified anti-Tau, 95-108 (PHF) antibody (clone SMI 51). Lane 1: Molecular weight marker; Lane 2: 20 µg of Alzheimer’s disease brain lysate; Lane 3: 20 µg of normal human brain lysate; Lane 4: 0.1 µg of recombinant Tau ladder protein. The blot was incubated with 1 µg/mL of the primary antibody overnight at 4°C, followed by incubation with HRP labeled goat anti-mouse IgG (Cat. No. 405306). Enhanced chemiluminescence was used as the detection system.

    IHC staining of purified anti-Tau, 95-108 (PHF) antibody (clone SMI 51) on formalin-fixed paraffin-embedded Alzheimer’s disease brain tissue. Following antigen retrieval using Sodium Citrate H.I.E.R (Cat. No. 928502), the tissue was incubated with 5 µg/ml of the primary antibody for 60 minutes at room temperature. BioLegend´s Ultra-Streptavidin (USA) HRP kit (Multi-Species, DAB, Cat. No. 929901) was used for detection followed by hematoxylin counterstaining, according to the protocol provided. The image was captured with a 40X objective. Scale bar: 50 µm

Description

Tau protein promotes microtubule assembly and stability. Tau is abundant in neurons of the central nervous system, and is expressed at low levels in astrocytes and oligodendrocytes. Abnormal hyperphosphorylation, aggregation, and toxic gain of function of tau is associated with several neurological disorders, including Alzheimer’s disease (AD). The major building block of neurofibrillary lesions in AD brains consists of paired helical filaments (PHFs) of abnormally hyperphosphorylated tau. Six isoforms of tau are generated by alternative splicing of the MAPT gene. These isoforms are distinguished by the number of tubulin binding domains, 3 (3R) or 4 (4R), in the C-terminal of the protein and by one (1N), two (2N), or no (0N) inserts in the N-terminal domain. Tau isoforms are differentially expressed during development.

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 1.0 - 5.0 µg per ml. For immunohistochemistry on formalin-fixed paraffin-embedded tissue, a concentration of 5.0 µg/ml is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

SMI 51 reacts with microtubule-associated protein tau independently of its degree of phosphorylation. This antibody reacts strongly with paired helical filaments in Alzheimer disease while its reaction with Tau in normal human tissue is relatively weak. The antibody recognizes the 95 to 108 sequence of Tau (AGIGDTSNLEDQAA) in a conformation partially dependent on serine in position 101.

Antigen Details

Structure
Unmodified Tau isoforms have an apparent molecular weight ranging from 33-79 kD. Additional high and low molecular weight Tau species have been observed in brain tissues.
Distribution

Tissue distribution: Central nervous system, peripheral ganglia and nerves, kidney, skeletal, and heart muscle.
Cellular distribution: Cytoskeleton, nucleus, plasma membrane, and cytosol.

Function
Tau promotes microtubule assembly and stability. The short tau isoforms allow plasticity of the cytoskeleton whereas the longer isoforms may preferentially play a role in its stabilization.
Interaction
Tau interacts with Sequestosome-1, Peptidyl-prolyl cis-trans isomerase FKBP4, Casein kinase I isoform delta, Serine/threonine-protein kinase Sgk1, Laforin, and alpha-synuclein.
