title: Photochemiluminescent detection of antiradical activity. I. Assay of superoxide dismutase.
abstract: The luminol sensitized photogeneration of superoxide radicals was combined with their luminol-dependent chemiluminescent detection. The inhibition of chemiluminescence by superoxide dismutase (SOD) versus enzyme concentration in reciprocals was strongly linear. The amount of SOD notable for 50% inhibition was between 115 and 500 ng for different enzyme preparations.
