Sanitation And Cryopreservation

Commited to providing genetically standardized models 


The microbiological status of rodents can have a major impact on the results and reproducibility of experiments. For that reason it is generally accepted to specify the microbiological status of the animals used.

Introduction of animals into a facility, maintenance and breeding of lines and the conduction of animal experiments all demand a specified and standardized health status and strict precautions to prevent introduction of pathogens into a facility. Preimplantation stage embryo transfer is a reliable and well established method to sanitize rodents with an unknown or compromised health status to a defined SPF health status.


Health monitoring program

InnoSer runs a health monitoring program based on the FELASA 2014 recommendations extended with Murine Noro Virus. Upon request the testing panel of infectious agents can be extended and more defined health statuses can be reached and maintained. To derive animals of a specified health status InnoSer offers sanitation service by embryo transfer on your demand and according to your health monitoring program needs.



Mouse models should be conserved by cryopreservation to:

  • protect your valuable mouse lines against physical or microbiological disasters
  • keep them harmless from genetic drift, genetic contamination or an unexpected drop in reproductive capacity
  • reduce the amount of animals needed to maintain a breeding colony.

InnoSer offers a cryopreservation service for freezing and storage of embryos and sperm.


We offer sanitation and cryopreservation services via our partner in Germany.

AAALAC Accreditation

InnoSer has earned the AAALAC accreditation, demonstrating our commitment to responsible animal care and use. AAALAC International is a nonprofit organization that promotes the humane treatment of animals in science through voluntary accreditation and assessment programs. Our accreditation is valid for three years, incl. 2023. Read more about the AAALAC accreditation programme here.


Animal Welfare

The 3Rs impact everything from policy and regulatory change to the development and uptake of new technologies and approaches. This is why Innoser has ongoing commitment and monitoring of these processes. The steps we practice maximize our ability to replace, reduce and refine animal involvement and facilitate our commitment to these principles when it comes to research and drug development.
