2-cell-embryo.jpgWe recommend the cryopreservation for all essential strains to ensure that a back-up is available for unforeseen problems and to protect their current health status.

The transgenic core offers the cryopreservation of embryos using a controlled rate freezer and storage in two independent liquid nitrogen tanks. Viability following the freezing process is confirmed either by thawing and assessing the embryos' ability to survive in vitro or by transferring the thawed embryos to recipient females to assess their in vivo viability.
