WebTau (Neurofibrillary tangle protein, Paired helical filament-tau, PHF-tau) Tau is a microtubule-associated protein found predominantly in neuronal axons of the vertebrate brain. Human tau exists as six different isoforms that result from alternative splicing of the single transcript derived from a gene located on chromosome 17. WebThe MN1050 immunogen is partially purified human PHF-Tau. MN1050 detects PHF-tau (Thr181) which has a predicted molecular weight of approximately 79 kDa. Tau is a neuronal microtubule-associated protein found predomitly on axons. The function of Tau is to promote tubulin polymerization and stabilize microtubules.
