Description :Rabbit Polyclonal Antibody

Species :Rabbit

Tag :

Expression System:

Sequence :

Specificity :Recognizes the TAU protein phosphorylated at serine 416

Cited Applications :WB

Cross Reactivity :Human, Mouse, Rat, Bovine, Canine and non-Human Primate

Host :Rabbit, IgG

Immunogen :Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser416 conjugated to KLH

Purification :Affinity Chromatography

Stability :Store at 4oC (add 0.1% NaN3) for several months, and at -20oC for longer periods. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.

Sample Data :Western blot of rat brain homogenate showing specific immunolabeling of the ~59, 65, 68kDa Tau isoforms phosphorylated at Ser416 (control). Immunolabeling is blocked by preadsorption with the phospho-peptide used as antigen (Peptide) but not by the corresponding dephospho-peptide (not shown).

Scientific Background :The Tau families of proteins function to stabilize the microtubules by binding to them. Thus they have a key role in promoting the formation of microtubules and axons. Six Tau isoforms have been identified, which are produced by alternative splicing (1). Phosphorylaition of Tau proteins regulates their association with microtubules (2). Deposits of Alzheimer's disease AD-associated proteins, such as hyperphosphorylated Tau, as well as other shared misfolded proteins, such as, β-amyloid precursor protein (βAPP), ubiquitin, and various chaperones and protein kinases are thought to play a pathologic role in the cognitive decline and muscular failure. Malfunction of Tau proteins is associated with microtubules disintegration and collapsing of the neuronal transport system (3). Serine 416 is a target for phosphorylation in vitro by CaM kinase II (4).
