  • Parthenogenic bovine oocyte activation
    Patent number: 5843754
    Abstract: A process of parthenogenic activation of mammalian oocytes which includes increasing intercellular levels of divalent cations in the oocyte; and reducing phosphorylation of cellular proteins in the oocyte. One method of accomplishing this is by introducing Ca.sup.2+ free cation, such as ionomycin, to the oocyte and then preventing phosphorylation of the cellular proteins within the oocyte by adding a serine-threonine kinase inhibitor, such as 6-dimethylaminopurine (DMAP).
