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.

COVID-19-related Disruptions
 March 19, 2020

Due to the current situation with COVID-19, we are operating with reduced staffing and there may be delays in responding to emails and phone calls at this time.  In addition, because of institutional restrictions and uncertainty with courier services and transportation, the RRRC is currently shipping and receiving live animals on a case-by-case basis.  For new requests, please contact us to discuss your needs.  For ongoing orders, we will continue to communicate frequently to keep you apprised of the status of your order.  Thank you for understanding.

RRRC Fully Operational
 June 14, 2020
The RRRC is fully operational at this time and we are excited to be able to assist researchers with all their rat-related needs. 
Rats on the rise
 July 20, 2021
Rats on the rise.  Ellen P. Neff (Lab Animal, 2021). After a genetic revolution in the 80s, mice overtook rats as the laboratory animal of choice for many researchers. But in recent years, the gene editing capabilities that had lagged a little for the larger rodent have been coming up to par with their murine cousins. Is a return to rats on the way?
Terms and Conditions
1.    If this strain is accepted, I agree, in a timely fashion, to:

a.  provide a detailed genotyping protocol and complete the breeding and husbandry form

b.  complete and submit the standard RRRC Donor Material Transfer Agreement (see
Donor MTA
) for my strain, which details the formal agreement between me, my institution and the RRRC for preservation and redistribution of my strain

c.  provide a recent health status report in advance of shipping this rat strain to the assigned facility

d.  provide this strain, within six months, in a single shipment of live rats or cryopreserved materials in the form and quantities that I have agreed to provide to the RRRC facility

e.  take responsibility for the cost of preparation and shipment of my rat strain to the RRRC facility.
2.     If I transfer my strain via cryopreserved embryos or germplasm, I accept the risk that it may not be possible to resuscitate my strain.

3.     I accept that the RRRC will maintain my strain as appropriate for the overall benefit of the entire strain repository resource, and that my strain may be maintained as a cryopreserved-only archive if demand is inadequate to justify maintenance of a breeding colony.

4.     I accept that there is a remote risk that it may not be possible to recover my strain from the cryo-repository. I understand that the RRRC will make a reasonable effort at resuscitation and I will not hold the RRRC responsible for the loss of my strain.

5.     I agree, when appropriate, to refer requests for my strain or material to the RRRC and to cite the RRRC as the supplying source in future publications referring to this strain.
