TAO2 (phospho Ser181) Antibody

TAO (thousand and one amino acid) protein kinases mediate signaling from carbachol to p38 MAPK and ternary complex transcription factors. This has led to the proposal that the TAO protein kinases play an essential role in signaling from physiological agonists to the stress-responsive p38 MAPKs. Autophosphorylation of TAO may play a role in the mechanism of TAO activation. The MEK binding domain of TAO is autophosphorylated on both serine and threonine residues and Ser181 is located within this domain.

TAO2 (Ser181) polyclonal antibody was raised against a synthetic phosphopeptide corresponding to amino acids residues surrounding the phospho Ser181 of TAO2.

For long term storage –80˚ C is recommended, but shorter term storage at –20˚ C is also acceptable as aliquots may be taken without freeze/thawing due to the presence of 50% glycerol. Stable for one year.

Human, mouse, rat and Xenopus have 100% amino acid sequence identity with the antigen used to raise the antibody. Applications include Dot Blots (DB) and Western Blots (WB) . Suitability for Immunohistochemistry (IHC) has not been determined. When internally tested under ideal conditions the working dilutions were 1:1000 for DB and WB.
