Fig. 5.

Cytoplasmic MPM2 proteins increased steadily during maturation. Oocytes from the same cohorts as were used for the pTyr experiments were also sorted into sets, labeled and imaged for MPM2 epitope proteins (phosphorylation targets of Cdk1/MPF). Oocytes in this figure represent single sections at the central plane of oocytes from a single set all imaged together in order to show the changes in fluorescence intensity at different stages of maturation to demonstrate the original images similar to Fig. 2 for pTyr
