FIG. 5.

Preimplantation expression of Ezh1 and Ezh2 in the early mouse embryo. RT-PCR was used to detect Ezh1, Ezh2, and Gapdh transcripts in total RNA preparations from wild-type oocytes, fertilized oocytes, morulae, and blastocysts. As a control, RT-PCR was also performed on total RNA from spleen tissue.
