Figure 1From: Essential role for poly (ADP-ribosyl)ation in mouse preimplantation developmentTransient upregulation of poly (ADP-ribosyl)ation in fertilized and parthenogenetic 1-cell embryos A: fertilized embryos, B: parthenogenetic embryos. Poly ADP-ribose polymers were detected with an anti-PAR antibody and a fluorescein-labeled (green signal) second antibody, as described in Methods section. Nuclei were counterstained with DAPI.Back to article page
