Wallenberg laboratory animal facility (KM-W)
KM-W at Karolinska Institutet is an animal facility enabling care and use of mice based on a barrier concept.

Research conducted in Wallenberg laboratory focuses on areas such as stem-cell and cancer research, regenerative medicine and brain diseases.
The facility
The Wallenberg laboratory is the first facility developed according to the barrier concept at KI. The barrier concept aims to standardize animal health status and facilitate collaboration between research groups at KI. There are at present three different barriers in the facility: Barrier A, B and D.
The facility comprises
- A core-breeding unit (at B-barrier)
- A transgenic production unit (at B-barrier, read more about KCTT)
- A D-barrier for short-term/mid-term housing and experiments
- An import portal, a unit for quarantine of imported living animals (A-barrier)
Offered services
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 use soundproof laboratories where you can perform behaviour tests on animals. Animals can only enter the core-breeding after embryo transfer.
Core-breeding
The core-breeding unit provides a unique possibility to reduce breeding of animals in the research units. Read more about core breeding at the Wallenberg laboratory.
