| Product description | 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®.1) Svenningsson, P., Tzavara, E.T., Carruthers, R., Rachleff, I., Wattler, S., Nehls, M., McKinzie, D.L., Fienberg, A.A., Nomikos, G.G.and Greengard, P., "Diverse psychotomimetics act through a common signaling pathway," Science, 302 (2003) 1412 - 1415. |
| Immunogen | DARPP-32 (Thr34) polyclonal antibody was raised against a synthetic phosphopeptide corresponding to amino acids residues surrounding the phospho Thr34 of DARPP-32. |
| Modification | p-Thr34 |
| Clonality | Polyclonal |
|---|---|
| Host Species | Rabbit |
| Tested Applications | WB |
| 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. | |

| Storage Instructions | 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. |
| Storage Buffer | 100 uL in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 ug per mL BSA and 50% glycerol. |
