the mu receptor specificity of bam alkylation was demonstrated by the ability of bam alkylated membranes to still bind the delta-selective peptide [ 3h ] [ d-penicillamine2 , d-penicillamine5 ] enkephalin ( dpdpe ) and ( - ) - [ 3h ] bremazocine in the presence of mu and delta blockers , selective for kappa binding sites .
