General description

Tau is a microtubule-associated phosphoprotein that is present in the axons of nerve cells. It stabilizes microtubules and mediates the polymerization of tubulin. Phosphorylation of Tau regulates its cellular functions. Hyperphosphorylation of Tau has been linked to neurodegenerative disorders such as Alzheimer’s disease . Anti-phospho-Tau (pSer404) antibody specifically reacts with Tau (pSer404) (45-68 kDa) in humans, mice and rats.

Physical form

Solution in Dulbecco′s phosphate buffered saline (without Mg2+ and Ca2+), pH 7.3, with 50% glycerol, 1.0 mg/ml BSA (IgG and protease free) and 0.05% sodium azide.


Anti-phospho-Tau (pSer404) antibody may be used in western blot (1:1000), immunoblot (1:1000) and immunohistochemistry.
