in a novel technique designed to determine the specific activity of small quantities of tritiated s-adenosylmethionine , high performance liquid chromatography with electrochemical detection was used to measure the amount of adrenaline formed from unlabelled noradrenaline , in the presence of phenylethanolamine-n-methyltransferase and tritiated s-adenosylmethionine .
