A new colorimetric method is presented for the determination of serum isocitric dehydrogenase activity. This is based on the determination of 2-oxoglutaric acid formed in the enzyme reaction by means of the previously established selective color reaction of the acid. The method gives reliable results and is suitable to assay a large number of samples with a wide range of activity at the same time with 50μl of sample.
