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. 

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. 

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.
