Preliminary Study on Superoxide Dismutase in Eggs of Silkworm
The activity of superoxide dismutase in silkworm eggs was determined by means of polyacrylamide gel electrophoresis and NBT light reducing reaction.The results indicated that the SOD isozyme exhibited a main bright superoxide dismutase band and several dark bands in the gel.Its activity could be strongly inhibited by chloroform-ethanol and slightly inhibited by H_2O_2.So it could be considered that the Mn-SOD exhibited the main activity of superoxide dismutase in the silkworm eggs.
