Delivering Specialized Feline Disease Models and Comprehensive CRO Services
At YiJi Biology, we are dedicated to advancing the development of high-quality feline disease models and providing fully integrated preclinical CRO services to support veterinary drug and vaccine innovation.
Disease Model Development
We specialize in developing a wide range of disease models for cats and dogs, including naturally occurring genetic models, drug-induced models, and surgical models.
With extensive expertise and a proven track record, we offer reliable, high-fidelity animal models for various research applications.
Naturally Occurring Genetic Models
Breeding and genetic screening to develop naturally mutated disease models, such as feline hypertrophic cardiomyopathy (HCM).
Infectious Disease Models
Controlled infection studies using standardized viral and parasitic strains for infectious disease research and drug development.
Gene-Edited Models
Gene-edited models created via embryo microinjection and embryo transfer technologies for targeted disease research.
Induced and Surgical Models
Drug-induced and surgical models for testing vaccines, pharmaceuticals, and other companion animal health products.
Preclinical CRO Services for for Companion Animal Drug Development
We offer full-spectrum preclinical CRO services across a wide range of species, including cats, dogs, rabbits, rats, and mice.
Our highly customized services cover everything from study design to model development and data analysis, ensuring flexible, client-focused solutions.
Efficacy Studies
