Restrictions
For Research Use only
Format
Lyophilized
Buffer
PBS, pH 7.4, containing 0.02 % sodium azide
Preservative
Sodium azide
Precaution of Use
WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
Storage
4 °C/-20 °C
Storage Comment
The antibody is stable in lyophilized form if stored at -20°C or below. The reconstituted antibody can be stored for 2-3 weeks at 2-8°C. For long term storage, aliquot and store at -20°C or below. Avoid repeated freezing and thawing cycles.
DARPP-32 (Dopamine- and cAMP-Regulated Neuronal Phosphoprotein, Mr 32 kDa), also known as PPP1R1B, is expressed in medium-sized spiny neurons that also express dopamine D1 receptors. It is a bifunctional signaling molecule that controls serine/threonine kinase and serine/threonine phosphatase activity. Both dopaminergic and glutamatergic (NMDA) receptor stimulation regulate the extent of DARPP32 phosphorylation, but in opposite directions. Dopamine stimulates phosphorylation of DARPP-32 through dopamine D1 receptors and activation of PKA. PKA phosphorylation of DARPP-32 at Thr34 converts it into an inhibitor of protein phosphatase 1. DARPP-32 is converted into an inhibitor of PKA when phosphorylated at Thr75 by cyclin-dependent kinase 5 (CDK5).Rabbit Anti-DARPP-32 Polyclonal Antibody is developed in rabbit using a KLH-coupled synthetic peptide within residues 150-200 of human DARPP-32 (Swiss Prot: Q9UD71).
