After 13 years of accumulation, Medicilon has now completed the establishment of more than 200 tumor animal models. At the same time, Medicilon’s pharmacological team has also established 50 in the fields of digestive system, metabolic diseases, central nervous system and immune inflammation. A variety of animal models are available for customers to choose from. Medicilon’s pharmacodynamic animal model was developed under the cooperation of Medicilon and MPI Research and passed AAALAC certification and conformed to the multinational GLP standard animal room environment. After that, it has been verified by various parties under the independent leadership of Medicilon’s expert team. Tested, the number and category of completion have been steadily increasing year by year. So far, it has been highly recognized by many customers in the industry and has formed a complete medicinal animal model library.
Medicilon can provide various animal models (including renal failure model, anemia animal model, gastric acid secretion animal model, and gastric ulcer model) to test drug effectiveness according to client needs. We can conduct tests on typical digestive system diseases, including gastric acid secretions, gastric ulcers, and renal failure, using rats as subjects.
Now that Medicilon’s pharmacodynamic team has joined Dr. Wenxin Dong. Dr. Dong has profound knowledge in the fields of depression, Alzheimer’s, pain, anxiety, Parkinson’s disease, etc. I believe that with Dr. Dong’s joining, Medicilon’s efficacy In terms of service, a more satisfactory answer sheet will be delivered.
