Fig. 8. Specific activity levels of hydrolases in different yolk granule (YG)
fractions during days 0 and 3 of development. (A) Acid phosphatase activity
levels. (B) Cathepsin D activity levels. White bars, activity on day 0; gray
bars, activity on day 3. Values are means ± s.e.m. of 3 different
experiments. EH, total egg homogenate. *Statistically significant
difference (P<0.05, t-test).
