Fig. 2. The effect of rbHsc70 on nuclear envelope breakdown (NEB) in fertilized sea urchin eggs. Fertilized sea urchin eggs were incubated in varying concentrations of Hsc70, and the times to NEB and cleavage were observed. Exogenous Hsc70 reduced the time to NEB at all concentrations tested. The difference between Hsc-treated and control eggs was statistically significant at 5 µg ml–1 Hsc, as indicated by the asterisk (P<0.05). Values are means ± s.e.m. N=6 replicate experiments in which at least 100 eggs were observed.
