Quinpirole reduces evoked dopamine release.

Assay Type: Ex Vivo
Species: Mouse
Voltammetry experiments were used to measure evoked dopamine release. Quinpirole (30nM) reduces dopamine release considerably (near IC50 in dorsal striatum), which was reversed by sulpiride (600nM). Drug works every time!
Goes into water well. We usually make up a 1 mM stock for many experiments.
