Rederivation to pathogen-free status via embryo transfer requires submission of 5 males, 10-24 weeks of age and 10 females, 7-12 weeks of age. You will receive all recovered pups after genotyping and health monitoring assays are performed.
Resuscitation and rederivation procedures are performed in pathogen-free barrier facility, and clean surrogate mothers purchased from commercial vendor are used for embryo transfers. You will receive the litters with confirmed genetics and pathogen-free health status.

In Need of a New Rat Model?
Need a new rat model? The RRRC in conjunction with the MU Animal Modeling Core (AMC) can assist with the generation of transgenic rats, create knock-out and knock-in rats using CRISPR/Cas9 technology and genetically manipulate rat embryonic stem cells to make chimeric animals. Contact us to discuss your rat model needs and how we can help.
Laboratory Animal Genetic Reporting (LAG-R) Guidelines Published
The LAG-R framework (Laboratory Animal Genetic Reporting) is a set of guidelines to support more complete documentation of the genetic make-up of animals of all species that are used in research, with the aim of bolstering reproducibility, reliability, and overall scientific rigor. See Nature Communications (https://doi.org/10.1038/s41467-024-49439-y).
GRCr8: A new rat reference assembly is now available.
GRCr8 (GenBank NCBI # GCA_036323735.1) is the latest version of the rat reference genome assembly. See the Genome Reference Consortium (GRC) blog for more details.
