title: Differential assay of choline acetyltransferase activity in human neuroblastomas and cloned adrenergic neuroblastoma of mouse.
abstract: A differential assay for the determination of choline acetyltransferase activity in neuroblastoma is described, and the importance of using the differential assay is discussed. In addition, changes in cholinergic-adrenergic activity of cloned adrenergic neuroblastoma cells after serial transplantations are reported. The changes of the cholinergic activity could not be detected precisely without the use of the differential assay.
