Need a New Rat Model?
 March 21, 2017
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.
The RRRC has continued to refine cryopreservation techniques in the rat.  Improvements to intracytoplasmic sperm injection (ICSI) now allow sperm cryopreservation for a cost effect means of archiving large collection sets of rats.
