title: Methionine-enkephalin precursor in neuroblastoma x glioma hybrid cells: in vivo and in vitro evidence.
abstract: The peptides obtained by proteolysis of both extracted proteins and in vitro translation products from Neuroblastoma x Glioma hybrids were purified by means of HPLC and then submitted to radioimmunoassay. Met-Enkephalin and Met-Enkephalin sulphoxide immunoreactivity was found.
