Anti-Tau (K225) Antibody

A rabbit polyclonal reagent from Antibodies.com targets the Tau protein at the lysine 225 (K225) residue, supplied as 50 µl of liquid at 1 mg/ml in phosphate buffered saline (PBS) with 0.05% sodium azide at approximately pH 7.2 for direct use in western blot workflows.

Tau is a microtubule-associated protein abundant in neuronal axons, and its hyperphosphorylation and aggregation are hallmarks of Alzheimer's disease and related tauopathies. The K225 residue sits within a region frequently modified in pathological tau, making this antibody relevant to studies of post-translational modification, isoform expression, and disease-related accumulation in neural tissue.

Validated for western blot application, the unconjugated antibody detects tau in human, mouse, and rat samples, enabling cross-species comparative work. The polyclonal format provides recognition of multiple epitopes surrounding the K225 site, supporting experiments on processed or fragmented tau species. Store refrigerated and protect from light; aliquot to avoid repeated freeze-thaw cycles. For research use only.
