Animal experimental core facilities

At Karolinska Institutet, the managing organisation for all aspects of animal experimentation in research is Comparative Medicine. Our scientists also have access to animal facilities managed by the Karolinska University Hospital.

Animal Behavior Core Facility (ABCF)

The Animal Behavior Core Facility (ABCF) is the new core facility at Karolinska Institutet for behavioral studies in mice and rats. ABCF is designed to provide optimal environment, state-of-the-art instrumentation and technical/educational support to perform behavioral tests ranging from basic phenotype characterization to advanced analyses.

Import Portal

Generally, laboratory animals imported to animal facilities have to go through quarantine first due to unsure or unsatisfactory health status. The Import Portal is a quarantine core-facility managed by Comparative Medicine (KM).

More about the portal


Manipulation of gene expression during mouse development is a powerful tool for querying the role of specific genes in development and disease. Infinigene is a facility which utilizes ultrasound-guided nano-injection to introduce DNA-modifying agents during embryonic development, or in adult mice.
