Simple, efficient and successful vitrification of bovine blastocysts using electron microscope grids

This study demonstrates that higher survival of vitrified–thawed bovine blastocysts can be obtained using electron microscope (EM) grids as embryo containers at freezing, rather than plastic straws. In-vitro produced day 7 bovine blastocysts after in-vitro fertilization (IVF) were vitrified on grids...
