Description
We constructed one-cell stage embryos by maternal pronuclear (mPN) transfer having B6 ooplasm, B6 paternal PN (pPN), and either B6 or C3H mPN (BBB and BCB, respectively). We collected embryos of each type that were either treated (BBB+a, BCB+a) or untreated with -amanitin (BBB, BCB) at the two-cell stage for microarray analysis.
