Activity staining of superoxide dismutase isoenzymes and their sensitivity to H₂O₂. The source of enzymes was Dunaliella salina CCAP 19/20 cells from active growth as well as stress growth phases. GP_Control, green-phase control cells; Cu, copper; Mn, manganese; IL, improved lane (H₂O₂ treated GP_control lane) showing five achromatic bands after adjustment of brightness and contrast of selected region of the gel.
