| pubmed-article:2828973 | pubmed:abstractText | The binding of the delta selective agonist [3H]DPDPE to diencephalic rat brain tissue was examined. Although most material examined gave rise to a single receptor model, one commercial preparation (Amersham, batch 8) suggested a two receptor model. Purification by HPLC removed a minor component and restored a single receptor model to the major component. | lld:pubmed |
