title: Strain differences in opiate receptors in mouse brain.
abstract: Various opiate ligands were bound to brain membranes of mice of the Recombinant Inbred System. The specific binding of low levels of [3H]naloxone, [3H]dihydromorphine and [3H]ethylketocyclazocine was disturbed in a similar fashion among the inbred strains, and in a pattern different from that observed for [3H](D-Ala2,D-Leu5)-enkephalin. The results indicate that the inbred strains differ in mu- and delta-type binding and support the concept of multiple opiate receptors in mouse brain.
