Is thiamine pyrophosphatase a reliable marker of the neuronal Golgi apparatus? A critical analysis.
The thiamine pyrophosphatase histochemical technique is believed to be a suitable approach to the selective staining of the Golgi vesicles of all animal cells, icluding the neuron. However, during the past decade a considerable number of data have been published, suggesting that the TPPase is in general a membrane-associated enzyme in the brain, which can be found in subcellular fractions other than Golgi lamellae. It has therefore become necessary to reconsider the view that thiamine pyrophosphatase is an exclusive marker enzyme of the Golgi apparatus.
