Characterisation of brain D2 dopamine receptors solubilised by lysophosphatidylcholine

Brain D2 dopamine receptors have been solubilised using lysophosphatidylcholine. The inclusion of proteinase inhibitors during solubilisation enables a preparation to be obtained containing a high proportion of solubilised D2 receptors with pharmacological properties similar to those of membrane-bound D2 receptors.
