Gamma radiation to enucleate avian eggs efficiently to enable donor nucleus transfer

摘要

A method of enucleating an egg by exposing the egg to gamma irradiation is described. The dose of gamma irradiation used is sufficiently high to halt development of the egg or embryo derived therefrom directed by the nucleus of the irradiated egg, but sufficiently low to enable development of the egg or embryo directed by a nucleus transferred into the enucleated egg.
