Animal biobanking for research and conservation

Why CryoArks?

Have you ever felt frustrated that you cannot access key samples for an animal genetics or genomics project? And would you know how to go about accessing such samples? Do you struggle to know how to best archive your samples? If you answered “Yes” to any of these questions, CryoArks is here to help!

The CryoArks biobank is an initiative that aims to bring together the diverse collections of animal frozen material found in museums, zoos, research institutes and universities across the UK to make them accessible to the UK’s research and conservation community.

A UK network of zoological biobanks that maintain frozen collections of animal genetic material to be used responsibly and sustainably in a wide range of applications that will further research knowledge and contribute to species conservation.
