The invention relates to a purified somatostatin receptor which is purified at least about 30,000-fold over the receptor which is membrane-bound. The invention also provides pharmaceutical compositions containing the receptor and antibodies to the receptor.

Purified active somatostatin receptor

The receptor:ligand complex is applied to a solid phase substrate which binds the complex by specifically binding the ligand. The receptor is dissociated from the substrate bound receptor:ligand complex with an eluant capable of releasing the receptor from the ligand and leaving the ligand bound to the solid phase substrate. GTP containing eluants are effective. The receptor is recovered from the eluate and optionally subjected to further purification.
