Description_x000D_ Immunogen_x000D_ Peptide sequence around phosphorylation site of serine 404 (D-T-S(p)-P-R), according to the protein MAPT._x000D_ Target description_x000D_ Promotes microtubule assembly and stability, and might be involved in the establishment and maintenance of neuronal polarity. The C-terminus binds axonal microtubules while the N-terminus binds neural plasma membrane components, suggesting that tau functions as a linker protein between both. Axonal polarity is predetermined by tau localization (in the neuronal cell) in the domain of the cell body defined by the centrosome. The short isoforms allow plasticity of the cytoskeleton whereas the longer isoforms may preferentially play a role in its stabilization._x000D_ Physical form_x000D_ Solution in phosphate-buffered saline containing 0.02% sodium azide and 50% glycerol_x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Features and Benefits_x000D_ Evaluate our antibodies with complete peace of mind.
