Abstract:
Superoxide dismutase (SOD) activity in 20 skin specimens from healthy individuals measured by the electron spin resonance-spin trapping method was 7.08 U +/- 0.41 U/mg protein (mean +/- SE). This method may be useful in the determination of SOD, since it requires a shorter time (approx. 3 min) and a smaller amount of specimen (approx. 30 mg) than previously reported methods other than the EIA method.
