General description
Tau is a neuronal microtubule-associated protein found predominantly on axons and functions to promote tubulin polymerization and stabilize microtubules. Tau, in its hyperphosphorylated form, is the major component of paired helical filaments (PHF), the building block of neurofibrillary lesions in Alzheimer′s disease (AD) brain. Hyperphosphorylated Tau is also found in neurofibrillary lesions in a range of other central nervous system disorders. Hyperphosphorylation impairs the microtubule binding function of Tau, resulting in the destabilization of microtubules in AD brains, ultimately leading to the degeneration of the affected neurons. Numerous serine/threonine kinases, including GSK-3beta, protein kinase A (PKA), cyclin-dependent kinase 5 (cdk5) and casein kinase II (CK2), phosphorylate Tau. Phosphorylation of threonine 205 is catalyzed GSK-3beta and cdk5 in vitro.
Immunogen
Synthetic peptide of amino acids surrounding the phosphoThreonine 205 site of human Tau.

This Anti-Tau phospho Threonine 205 Antibody is validated for use in WB for the detection of Tau phospho Threonine 205.
Western blot: 1:1,000. Suggested blocking buffer is 5% BSA-TBST for one hour at room temperature. Suggested antibody dilution buffer is 3% BSA-TBST. Suggested antibody incubation time is 2 hours at room temperature..
Optimal working dilutions must be determined by the end user.
Biochem/physiol Actions
Tau phosphoThreonine 205. The antibody recognizes Tau pThreonine 205 in samples of recombinant human Tau treated with GSK-3beta for 45 minutes.. The reactivity of the antibody is blocked with the pThreonine 205 peptide but not the non-phosphopeptide or a generic phosphoThreonine-containing peptide.
Preparation Note
Maintain at -20°C in undiluted for up to 6 months after date of receipt. Avoid repeated freeze/thaw cycles. Do not store in a self defrosting freezer.
