DARPP 32 (phospho Thr34) Antibody

• Background:

  DARPP-32, a dopamine (DA) and cAMP-regulated ~32k phosphoprotein that is associated with dopaminoceptive neurons bearing D-1 receptors in the basal ganglia. The protein inhibits protein phosphatase I when it is phosphorylated on Thr34. In contrast, when DARPP-32 is phosphorylated on Thr75 the protein acts as an inhibitor of PKA. Phosphorylation of DARPP-32 is thought to play a critical role in the regulation of dopaminergic neurotransmission. In addition, the activity of DARPP-32 is also thought to play important roles in the actions of alcohol, caffeine and Prozac®.

• NCBI Gene ID:

  360616

• Swiss Prot:

  Q6J4I0

• Accession Number:

  Q6J4I0

• Host:

  Rabbit

• Reactivity:

  Human, Mouse, Rat, Frog

• Immunogen:

  DARPP-32 (Thr34) polyclonal antibody was raised against a synthetic phosphopeptide corresponding to amino acids residues surrounding the phospho Thr34 of DARPP-32.

• Clonality:

  Polyclonal

• Conjugation:

  Unconjugated

• Type:

  Primary Antibodies

• Field of Research:

  Neuroscience, Phospho-Specific

• Purification:

  Affinity Purified

• Concentration:

  Batch dependent

• Modification:

  Phospho-Specific

• Shipping Conditions:

  Blue Ice

• Storage Conditions:

  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. Stock solutions are stable for a minimum of 1 year at -20˚ C.

• Calculated Molecular Weight:

  32

• Specificity:

  DARPP 32 antibody is specific for the ~32k DARPP-32 phosphorylated at Thr34.

• Applications Notes:

  Applications include Dot Blots (DB) and Western Blots (WB) . Suitability for Immunohistochemistry (IHC) has not yet been determined. Rabbit anti-DARPP-32 (Thr34) recognizes human, mouse, and rat forms of the protein. When internally tested under ideal conditions the working dilutions were 1:1000 for DB and WB.
