The Wallenberg laboratory at Karolinska Institutet is an animal facility enabling care and use of small rodents based on a barrier concept. The facility is the host of KI mouse model core facility umbrella (KIMM).
Research conducted in Wallenberg laboratory focuses on areas such as stem-cell and cancer research, regenerative medicine and brain diseases.

The facility provides a wide range of qualified services to the scientific community for work with different mouse strains. All mice in the facility are housed in ventilated cages in a strictly controlled environment. Animal experiments can be performed in the state-of-art laboratories at the research units. Experiments with animals infected with microorganisms (risk group 2) can be performed in fully equipped biosafety laboratories (level 2). It is also possible to perform behaviour tests on animals in soundproof laboratories. Animals can only enter the core-breeding and research units after embryo transfer or after having been directly shiooed from an approved supplier (valid only for C-barrier).
