Catalase in manipulation buffer enhances the developmental competence of DNA-injected embryos.

Abstract excerpt

To improve the efficiency of transgenesis, we investigated the effects of a radical scavenger during microinjection on the development to blastocysts or pups of mouse pronuclear embryos, microinjected with the enhanced green fluorescent protein (EGFP) transgene. When embryos were microinjected in medium containing 0-1,000 units/ml catalase, the developmental rate to blastocysts was significantly higher (P<0.01)...
