Weather and Shipping

The welfare of the animals is of utmost importance and as we head into the summer months, inclement weather and excessive heat will delay/prevent shipments of live animals.  Be aware that hot temperatures between June and mid-September may negatively impact the ability of couriers to safely ship animals so please plan your live animal orders accordingly.

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.
