Anti-Tau phospho Serine 262 Antibody

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. Serine 262 can be phosphorylated by GSK-3beta, PKA, CamKII, MARK and has been found to be a major site in AD brain.

Western blot: 1:1,000. Suggested blocking buffer is 5% BSA-TBST overnight at 2-8?C. 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.

Tau phosphoSerine 262. The antibody recognizes Tau pSerine 262 in samples of recombinant human Tau treated with PKA for 45 minutes. The reactivity of the antibody is blocked with the pSerine 262 peptide but not the non-phosphopeptide or a generic phosphoSerine-containing peptide.

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.
