Descripción

Descripción general

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 MAPTL, MTBT1, TAU) gene (Gene ID 4137) in human. Extracellular plaque deposits composed of amyloid-β and intracellular neurofibrillary tangles (NFTs) composed of truncated and hyperphosphorylated tau are two neuropathological hallmarks of Alzheimer′s disease (AD). Tau pathology (tauopathy) can cause toxicity when the brain is devoid of amyloid plaques, and tangle pathology correlates better with clinical dementia than amyloid pathology. Abnormal processing of tau by hyperphosphorylation and proteolytic truncation contribute to the toxicity of tau. Tau also undergoes other types of posttranslational modifications, including glycosylation, ubiquitination, glycation, polyamination, nitration, and lysine methylation, which are believed to be important for its non-pathological functions, including polymerization and stabilization of microtubules. Alternative splicings result in multiple Tau isoforms, including five human Tau spliced isoforms with four C-terminal microtubule-binding repeats/domains (RD4) and four spliced isoforms that contain only three microtubule-binding domains (RD3) due to the absence of exon 10-conding sequence. Isoform-specific antibodies are useful tools for analyzing tau isoforms expression and distribution as well as pathological changes in the human brain.

Especificidad

Clone 7D12.1 targets an epitope sequence present in Tau spliced isoforms with four C-terminal microtubule-binding repeats/domains (RD4), including human isoforms PNS-tau, Tau-D, Tau-E, Tau-F, and Tau-G, but not Tau spliced isoforms that contain only three microtubule-binding domains (RD3) due to the absence of exon 10-conding sequence (human isoforms Fetal-tau, Tau-A, Tau-B, and Tau-C).

Inmunógeno

Epitope: Junction-flanking region coded by adjacent exons 9 & 10.

KLH-conjugated synthetic peptide (VQIINKKLDLSNVQSKC) corresponding to a junction-flanking sequence coded by adjacent exons 9 & 10 of Tau. The immunizing sequence is identical in human, rat, mouse and bovine.

Aplicación

Immunohistochemistry Analysis: A 1:50-250 dilution from a representative lot detected Tau 4-repeat isoforms in Alzheimer′s diseased (AD) human brain, as well as human kidney and non-AD brain tissue sections.
