A Colorimetric Method for the Estimation of Succinic Dehydrogenase Activity

A colorimetric method for the estimation of succinic dehydrogenase activity.

Many methods for the measurement of succinic dehydrogenase activity have been proposed (l-20). These have varied from measurement of the entire system of electron transport with oxygen as the final acceptor (5, 21), to the determination of succinic dehydrogenase activity itself (6, 9, 22). The assay of succinic dehydrogenase alone was made possible by the finding that phenazine methosulfate can...

Colorimetric estimation of succinic dehydrogenase activity by neotetrazolium chloride as a tumor sensitivity test to chemotherapeutic agents.

In the search for tumor sensitivity test to chemotherapeutic agents succinic dehydrogenase activity by neotetrazolium chloride was measured colorimetrically. The rate of formazan production was proportional to the amount of Ehrlich ascites tumor cells, accelerated by the addition of ascorbic acid, and inhibited by the addition of iodoacetic acid. The inhibitory rate of formazan production of tu...
