Synthetic peptide corresponding to CSYSKEVPEMEKRYGGFMRF of rat Enkephalin, Prepro (ppENK), conjugated to KLH.
Met-enkephalin (tyr-gly-gly-phe-met) and leu-enkephalin (tyr-gly-gly-phe-leu) are pentapeptides which compete with and mimic the effects of opiate drugs. Although interest in enkephalins stems largely from their possible role in the brain, the richest so
