[Superoxide dismutase in the nuclei of cerebral cortex cells of rats: isolation, properties, effect of ionizing radiation].
Superoxide dismutase (SOD) from rat brain cell nuclei has been distinguished. After chromatography on hydroxylapatite Sephacryl S200 and Mono S SOD can be purified 1200 times. It is Mn-depending enzyme, which has molecular weight 10 kDa and firmly associated with transcriptionally active chromatin. SOD is most active at high ion strength (1.2-2 M NaCl). The more sensitive method for SOD activity determination is suggested (modification of adrenaline autoxidation at pH 10.2).
