Figure 6.
Histone H1 kinase activity in MII oocytes, which matured in vitro, and were fertilised during maturation, and in in vitro matured oocytes, which were not fertilised. (A) autoradiography showing the intensity of incorporation of [32P] into exogenous H1 histone in lysates prepared from MII oocytes. Each line corresponds to the activity prepared from 5 oocytes. (a) control, uninseminated oocytes, (b, c) oocytes, which were fertilised during maturation, 1 – 4 h after GVBD. (B) mean activity of histone H1 kinase in MII oocytes, which were fertilised during maturation and in MII oocytes, which were not fertilised. Differences between these two groups are not statistically significant (p > 0.05).
