Effect of the vitrification methods OPS and SSV, with inclusion of a synthetic ice blocker, on the viability of mice and bovine oocytes

Oocyte vitrification is a valuable tool for preservation of genetic material. This study compared the effects of vitrification in OPS and SSV, with addition of SupercoolTM X- 1000 (copolymer), on the viability of mature murine oocytes and immature bovine oocytes. Oocytes were vitrified in OPS and SSV, with addition of 0.1%, 1.0% copolymer and without copolymer, besides a control group with no vitr…
