Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified B
DARPP-32, a dopamine (DA) and cAMP-regulated ~32kD phosphoprotein that is associated with dopaminoceptive neurons bearing D-1 receptors in the basal ganglia,1 inhibits protein phosphatase I when it is phosphory 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 neurotransmission2. In addition, the activity of DARPP-32 is also thought to play important roles in the actions of alcohol, caffeine and Prozac®.
Catalog #D1075-03A
ApplicationsSuitable for use in Western Blot. Other applications not tested.
Recommended DilutionWestern Blot: 1-3ug/ml
Optimal dilutions to be determined by the researcher.
Storage and StabilityMay be stored at -20°C for short-term only. For long-term storage, store at -70°C. Aliquots are stable for at least 12 months at -70°C.

Clone TypePolyclonal
HostRabbit
Concentration10 mini-blots/100ul
FormSupplied as a liquid in 10mM Hepes, pH 7.5, 150mM NaCl, 0.1mg/ml BSA, 50% glycerol.
PurityPurified by immunoaffinity chromatography.
ImmunogenSynthetic peptide derived from amino acids surrounding the phosphorylated Thr34 residue of DARPP-32.
SpecificityReacts with human, mouse, and rat DARPP-32 proteins phosphorylated at Thr34. On Western blots, it identifies the target band at ~32 kD. Reactivity has been confirmed with rat caudate slices incubated in the presence of forskolin.
