title: A thin-layer chromatographic assay for measuring pineal hydroxyindole-O-methyltransferase activity.
abstract: A thin-layer chromatographic procedure for measuring pineal HIOMT activity is described, based on the methylation of NAS to melatonin. The method enables simple and accurate determination in small aliquots from a single pineal organ homogenate.
