Biochemical Hallmarks of Oxidative Stress-Induced Overactivation of Xenopus Eggs

Figure 2

Time and dose dependencies of egg overactivation by hydrogen peroxide. Panel (a) shows dynamics of morphological changes in the eggs overactivated by 100 mM hydrogen peroxide. Panel (b) presents time course of egg cortical contraction and overactivation after addition of 100 mM hydrogen peroxide. The untreated control (-H₂0₂) in panel (b) refers to overactivated phenotype. Panel (c) shows dose dependency of egg overactivation. Overactivated phenotype in panel (c) was counted in 240 min after addition of peroxide.
