Transgenic and Cryopreservation Services About us

The Transgenic and Cryopreservation Services offers specialized services of mouse reproductive biotechnology. We perform assisted reproduction techniques (in vitro fertilization) to ensure the preservation of infertile and/or endangered strains, aseptic rederivation by embryo transfer to improve the sanitary status of contaminated strains, import/export of strains with cryopreserved or refrigerated material, cryopreservation and archive of strains, and generation of new genetically modified models by additive classical transgenesis techniques or targeted mutagenesis.

The service has the following specialized equipment:

  • Heated dissecting microscopes.
  • Classic and benchtop CO2 incubators for In Vitro Fertilization.
  • Controlled-rate freezing unit.
  • Inverted Microscope with antivibration system, Eppendorf´s micromanipulators and Femtojet injector.
  • ESPACE 151 liquid nitrogen tank for safe storage of samples with auto filling system.

The services we offer are:

  • Sperm and Embryo Cryopreservation.
  • In vitro fertilization (IVF).
  • In vivo sampling of epididymal sperm.
  • Aseptic rederivation by embryo transfer.
  • Strain rescue.
  • Strain speed expansion through IVF.
  • Revitalizing of cryopreserved or refrigerated gametes and embryos.
  • Strain Import/Export by sperm, embryos or epididymis.
  • DNA or RNA pronuclear/cytoplasmic microinjection.
