title: A rapid micro scale method for the detection of lysopine and nopaline dehydrogenase activities.
abstract: A rapid and sensitive method has been developed to determine lysopine dehydrogenase (EC 1.5.1-) and nopaline dehydrogenase activities in crown gall tumour tissues. By this method, enzyme activities as low as 0.2  micrometerol octopine or nopaline per h per g fresh weight tumour tissue can still be detected. In non-infected young pea seedlings, no lysopine dehydrogenase activity was detected.
