Our Anti-DARPP-32 rabbit polyclonal primary antibody from PhosphoSolutions is produced in-house. It detects rat DARPP-32 and is antigen affinity purified from pooled serum. It is great for use in WB, IHC.

DARPP-32 is a dopamine (DA) and cAMP-regulated ~32 kDa phosphoprotein that is associated with dopaminoceptive neurons (Fienberg et al., 1998). The protein inhibits protein phosphatase I when it is phosphorylated on Thr-34. In contrast, when DARPP-32 is phosphorylated on Thr-75 the protein acts as an inhibitor of PKA (Bibb et al., 1999). 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® (Maldve et al., 2002; Lindskog et al., 2002; Svenningsson et al., 2002).

Rabbit
PPP1R1B
32 kDa
Synthetic peptide corresponding to amino acid residues from the N-terminal region of rat DARPP-32, conjugated to keyhole limpet hemocyanin (KLH).
Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
Liquid
Prepared from pooled rabbit serum via chromatography on an affinity column prepared with the N-terminal peptide used as antigen.
10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol.
WB: 1:1000
WB Brain: 1:1000
ICC: 1:250
Unconjugated
Specific for endogenous levels of the ~32 kDa DARPP-32 protein.
