Anti-Tau Antibody

The Tau protein (microtubule-associated protein tau, MAPT) is a neuronal microtubule-stabilizing factor critical for cytoskeletal integrity and axonal transport. This unconjugated rabbit polyclonal antibody from Antibodies.com targets the Tau protein and is validated for western blot and ELISA workflows, recognizing endogenous Tau across human, mouse, and rat sample types.

Supplied in a 100 µL vial format suitable for multiple experimental runs, the reagent supports immunoblotting of phosphorylated and total Tau species in brain tissue lysates, neuronal cell culture extracts, and postmortem homogenates relevant to Alzheimer's disease, frontotemporal dementia, and broader tauopathy research. The polyclonal recognition pattern detects multiple epitopes along the Tau sequence, useful when probing both 3R and 4R isoforms or full-length versus truncated species in neurodegenerative models.

As an unconjugated primary reagent, the antibody integrates into standard HRP- or fluorophore-conjugated secondary detection systems, offering flexibility for chromogenic western blot development, immunoprecipitation protocols, and ELISA plate capture setups. For research use only, this primary antibody should be stored refrigerated and aliquoted to minimize freeze-thaw cycles, preserving long-term binding activity.
