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.

Why Research Resource Identifiers (RRIDs) Are Important

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.
