Development of an analytical method to determine malondialdehyde as an oxidative marker in cryopreserved bovine semen
Yonny, Melisa Evangelina; Reineri, Pablo Sebastian; Palma, Gustavo Adolfo; Nazareno, Mónica Azucena (Royal Society of Chemistry, 2015)Frozen sperm is widely used in artificial insemination of cattle as well as other animal species. As a consequence of the freezing and thawing processes of semen, an excess of reactive oxygen species (ROS) are formed. ROS ... -
