Biological Support Unit

Our state-of-the-art Biological Support Unit (BSU) provides housing and care for pathogen-free rodents. It supports research across the Institute as well as providing services to private companies.



In February 2022 the facility completed accreditation for AAALAC International. This voluntary accreditation is evidence that the Institute and the BSU is taking extra steps to achieve excellence in animal care and use. Our animal technicians hold Home Office Personal Licences enabling the BSU to provide technical support for researchers. The team have a commitment to up-hold the highest standards of animal welfare in all aspects of their work.

The BSU is made up of four bio-science units, each performing a unique role in the provision of flexible services to meet the ever-changing needs of biological research. The four units are arranged around a central services unit which utilises robotic cage-washing technology and automated sterilisation processes to provide equipment and consumables to each unit. We have a mix of animal technicians and service technicians who perform daily husbandry duties and provide essential services to the facility.





As a founding signatory of the Concordat on Openness on Animals in Research, the Institute is committed to communicating and engaging the public about our use of animals in research. More information is available on our animal research pages. You can also request a virtual tour of the BSU, or attend a range of other events related to our use of animals in research by contacting our Public Engagement team. To find out more about why the Institute works with animals and what we achieve through this work, please visit our animal research pages.


The BSU is keen to help more people to find out about their work and job roles involved. The ‘work with us, learn with us’ pages contain more information about careers within the facility
