Descrição geral
Microtubule-associated protein tau (UniProt P10636; also known as Neurofibrillary tangle protein, Paired helical filament-tau, PHF-tau) is encoded by the MAPT (also known as TAU, MAPT1, MTBTL) gene (Gene ID 4137) in human. In Alzheimer′s disease (AD) pathology, accumulation of the microtubule-associated protein tau takes place primarily in the neurons. Tau accumulates in both the somatodendritic and axonal domains of neurons. Tau also accumulates in the soma as neurofibrillary tangles (NFTs). Cell death and synaptic lesions occur independently of NFT formation, and research indicates that NFT formation alone is insufficient for neurodegeneration, suggesting that soluble tau aggregates may be the more toxic and pathologically significant tau species. Tau oligomers are neurotoxic when applied extracellularly to cultured neuronal cells, and tau oligomers (but not fibrils) induce neurodegeneration and synaptic and mitochondrial dysfunction in vivo. Moreove, researchers are able to use tau oligomers as a reliable biomarker to differentiate AD brains from age-matched non-AD brains.
Especificidade
T22 specifically recognizes and neutralizes oligomeric tau, T22 does not show any significant reactivity toward monomeric tau, tau fibrils, Aβ oligomers, Aβ fibrils, α-synuclein oligomers, or α-synuclein fibrils (Lasagna-Reeves, C. A., et al. (2012). FASEB J. 26(5):1946-1959).
Imunogênio
Recombinant human Tau-441 (Tau-F, Tau-4, 2N4R isoform) oligomers (Lasagna-Reeves, C. A., et al. (2012). FASEB J. 26(5):1946-1959).
Aplicação
Dot Blot (Specificity) Analysis: A 1:1,000 dilution from a representative lot detected oligomeric tau, but not monomeric tau or tau fibrils.
Immunohistochemistry Analysis: A 1:245-1,000 dilution from a representative lot detected tau oligomers in frontal cortices from Alzheimer′s Diseased (AD) and Lewy Body Diseased (LBD) patients (Courtesy of Prof. Rakez Kayed, University of Texas, Galveston).
Immunofluorescence Analysis: A representative lot detected oligomeric tau in chronic traumatic encephalopathy (CTE) brain tissue sections, while little or no tau oligomer immunoreactivity was seen in non-CTE human brain sections. The tau oligomer immunoreactivity colocalized with that of tau pThr231 with a cis conformation, but not tau pThr231 with a trans conformation, between pThr231 and Pro232 (Kondo, A., et al. (2015). Nature. 523(7561):431-436).
Immunofluorescence Analysis: A representative lot detected oligomeric tau immunoreactivity in paraffin-embedded frontal cortex sections from Alzheimer′s diseased (AD) brains (Lasagna-Reeves, C. A., et al. (2012). FASEB J. 26(5):1946-1959).
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected oligomeric tau in chronic traumatic encephalopathy (CTE) in Tau Aggregate lysate.
Western Blotting Analysis: Representative lots detected oligomeric tau, but not monomeric tau, or any other oligomeric and fibrillar proteins (Wu J.W., et al. (2013). J. Biol. Chem. 288(3):1856-1870; Lasagna-Reeves, C. A., et al. (2012). FASEB J. 26(5):1946-1959).
Dot Blot Analysis: A representative lot detected tau oligomers, but not tau monomer or paired helical filaments (PHFs) (Lasagna-Reeves, C. A., et al. (2012). FASEB J. 26(5):1946-1959).
ELISA Analysis: Representative lots detected vitro formed tau oligomers as well as tau oligomers in PBS-soluble brain extracts from progressive supranuclear palsy (PSP) patients (Lasagna-Reeves, C.A., et al. (2012). Sci. Rep. 2:700; Lasagna-Reeves, C. A., et al. (2012). FASEB J. 26(5):1946-1959).
ELISA Analysis: A representative lot showed selective reactivity toward oligomeric tau, while exhibiting greatly reduced immunoreactivity toward tau fibrils, and no reactivity toward monomeric tau, or other protein oligomers or fibrils (e.g., Aβ, α-synuclein, or islet amyloid polypeptide) (Lasagna-Reeves, C. A., et al. (2012). FASEB J. 26(5):1946-1959).
Immunoprecipitation Analysis: Representative lots immunoprecipitated oligomeric tau from Alzheimer′s Diseased (AD), but not non-AD brains (Lasagna-Reeves, C.A., et al. (2012). Sci. Rep. 2:700; Lasagna-Reeves, C. A., et al. (2012). FASEB J. 26(5):1946-1959).
Neutralizing Analysis: Representative lots neutralized oligomeric tau toxicity to SH-SY5Y human neuroblastoma cells (Lasagna-Reeves, C.A., et al. (2012). Sci. Rep. 2:700; Lasagna-Reeves, C. A., et al. (2012). FASEB J. 26(5):1946-1959).
