Modifications in our rats offering

Dear partners,

JANVIER LABS is making the following changes to its rats offering:

• The commercialization of SPRAGUE DAWLEY HAIRLESS (SD Hairless) rats in their live form
  ceases. These models are available in their cryopreserved form.
• The commercialization of WISTAR KYOTO (WKY) rats in their live form will cease on 31/12/2024
  (date of the last deliveries). These models will remain available in their cryopreserved form.

These decisions were driven by the shifting demands within the research community, and the need to allocate
resources in a way that allows us to continue delivering the highest quality of models to the scientific
community as a whole.

Our team is available to provide any information you may need regarding the new supply conditions of WKY
and SD Hairless via revitalization, as well as guidance on alternative models that may be suitable for your
research.

Please feel free to reach out to us with any questions or specific needs you may have.

Thank you for your understanding and for your continued partnership.

Sincerely,

Anthony Clouard
Industrial Operations Manager
