Figure 3. a) A minimal vitrification device used as the carrier for vitrifying embryos. This one is a Cryolock (FujiFilm, Irving Scientific, California, USA). b) Embryos are loaded onto the tip (arrowed) in a 2 µl volume of vitrification solution. The excess solution is removed before plunging into liquid nitrogen.

A touch of glass: cryopreservation of equine embryos by vitrification

Mammalian embryos cryopreserve well when they are relatively small, contain a negligible blastocoele cavity and their structure allows for the passage of cryoprotectants into the cells. Equine embryos...
