The development of human diseases is highly complex. Directly using humans as experimental subjects to investigate disease mechanisms is limited by ethical concerns and safety risks, often slowing progress in biomedical research.

Animal models provide a powerful alternative by allowing researchers to manipulate variables that are impossible or difficult to control in humans. These models enable systematic observation, mechanistic studies, and translational comparisons with human diseases—greatly accelerating the understanding of disease progression and the development of preventive and therapeutic strategies.

Yeasen Biotechnology offers a comprehensive portfolio of animal disease modeling reagents, covering inflammatory, metabolic, neurological, cardiovascular, and cancer models. A detailed selection guide is provided below.
