This product detects a band of approximately 32kDa in rat caudate lysates.
This product is specific for rat DARPP-32, when phosphorylated at threonine 34.
DARPP-32 (also known as protein phosphatase 1 regulatory subunit 1B PP1R1B) is a dopamine- and cAMP-regulated phosphoprotein, which is principally expressed in striatal medium spiny neurons, and is thought to play a critical role in the regulation of dopaminergic neurotransmission.
DARPP-32 can act either as a phosphatase inhibitor or as a kinase inhibitor, depending on its relative state of phosphorylation . Phosphorylation at threonine 34 converts DARPP-32 into an inhibitor of protein phosphatase-1 (PP-1) whilst phosphorylation at threonine 75 switches the protein to an inhibitor of protein kinase A (PKA) .
Store at +4 °C or at -20 °C if preferred.
Storage in frost-free freezers is not recommended.
This product should be stored undiluted.
Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.
If stored in this manner, this product is stable for 12 months after receipt.
