  • Title: Quantitative succinate-dehydrogenase histochemistry. I. A Methodological study on mammalian and fish muscle.
    Author: Pool CW, Diegenbach PC, Scholten G.
    Journal: Histochemistry; 1979; 64(3):251-62. PubMed ID: 93099.
    Abstract:
    In enzyme histochemistry formazan production can be used as a measure for oxidative enzyme activity. The formazan deposits can be measured quantitatively per cell with a scanning and integrating microspectrophotometer. Optimal conditions are described for the estimation of histochemical succinate dehydrogenase activity in sections of fish bodymusculature and mouse soleus and plantaris muscle. It is shown that when proper measuring conditions are chosen a ditetrazolium salt (TNBT) can be used in quantitative enzyme histochemistry and that the optimal conditions for the histochemical succinate dehydrogenase reaction in muscle fibres of fish and mouse muscle are somewhat different for these two species. The differences in pH, temperature and succinate sensitivity are the most prominent.
