The unit provides high-level support in the field of animal genome modification (mice, rats and ruminants). We offer several techniques, such as pronuclear
microinjection, homologous recombination in embryonic stem cells, lentiviral injection, transposons and the revolutionary CRISPR / Cas9 system. We also provide cryopreservation, in vitro fertilization and embryo rederivation in mice. Besides, the unit supplies mice and rats with high genetic and health status for researchers within the institute and the region.
Since 2007 we have worked with national and international biotechnology companies offering in vivo biological assays in mice and rats, under GLP standards. We receive undergraduate and graduate students who do thesis using different technologies to obtain animal models. We also organize courses for technicians and scientists, and offer internships for technicians or veterinarians who administer their own services.
Our staff is member of organizations, such as the International Society for Transgenic Technologies (ISTT), the Institutional Articulation Committee (CAI), the
National Commission of Animal Experimentation (CNEA), the Uruguayan Association of Animal Science and Technology Laboratories (AUCyTAL), and the Federation of South American Associations for Laboratory Animal Science (FESSACAL)
