Shipping Policy
The shipping company (courier) is selected by the receiving institution. Upon transfer from the RRRC, animals become the responsibility of the shipper and any issues that arise during the shipping process are between the receiving institution and their chosen courier. Should shipping delays occur, it is the responsibility of the receiving institution to work with the courier to ensure successful shipment. The RRRC cannot be held responsible for loss of animals or health problems that occur once custody of the animals is assumed by the shipper.
If delays occur in shipping, the RRRC can work with the client and shipper to assist in determining an optimal solution. This may include, but is not limited to, having the shipper identify a local source to maintain animals in a temperature controlled environment, checking animal health and supplementing food and water. In cases where extended delay is inevitable, euthanasia may be required. In these situations, the RRRC will determine accessibility of replacement animals, but additional costs to the client (or shipper) will be incurred. Return of animals to the RRRC is not a viable option.

Plan ahead for the holidays
The University of Missouri, home of the RRRC, is closed for business for the holidays at the end of December/beginning of January. Please be aware that we will not be responding to inquiries, providing services or shipping materials from December 22, 2025 through January 2, 2026.
Why Research Resource Identifiers (RRIDs) Are Important
RRIDs are unique identifiers for key biological resources, genetically enigineered animals and reagents like antibodies. Piekniewska et al. document how use of RRIDs improves trackability. Importantly, better citation practices increase research rigor and reproducibility.
Animal Models and New Approach Methodologies (NAMs)
NAMs are lab (e.g., organoids and iPSCs) or computer-based methods intended to expand our tools for modeling human biology and disease. While this field is rapidly evolving, the need for animal models remains, especially for situations where a complex biological system is necessary. In addition, animal models serve as vital in vivo controls for the validation and verification of emerging NAMs.
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.
