Abstract

A proteolipid isolated from a lipid extract of mouse brain demonstrates stereospecific binding properties for levorphanol. It is present only in neuronal tissue and most abundant in the rhombencephalon. One component saturates at a concentration corresponding to maximum pharmacologic effect in vivo. The estimated mass is 60,000 daltons per bound opiate molecule.
