FeiFan's scientific research team has rich scientific research experience, based on the biomedical field, customer demand-oriented, for the majority of scientific research workers to establish a platform for the evaluation and optimization of experimental programs, animal experiments, cellular experiments, gene level experiments, protein level experiments, the overall subject of the collaborative services and so on.

Over the years, Feifan test adhering to the “professional, focused; fine, accurate” attitude to assist the majority of scientific research workers to complete hundreds of National Natural Science Foundation, the provincial Natural Science Foundation and municipal and regional fund projects, to provide customers with the optimization of the experimental design services and professional experimental solutions, to help research workers to shorten the research We have been widely praised for providing experimental design optimization services and professional experimental solutions to help researchers shorten their scientific research cycle and save experimental costs, so that their scientific research is sustainable.

Constructing animal models of eight common systems: animal model construction, animal feeding, experimental animals (rats, mice, guinea pigs, rabbits, dogs, candidates, etc.) only need to provide modeling drugs or reagents. Nervous system drug experiment, cardiovascular system drug experiment, digestive system drug experiment, urinary system drug experiment, respiratory system drug experiment, endocrine drug experiment.

Feifan Testing has been deeply cultivating in the field of drug medicines for many years, utilizing zebrafish model experiments to provide drug companies with biological testing services such as drug efficacy and safety evaluation, toxicity testing, preclinical experiments, traditional Chinese medicine evaluation and screening, and screening of active ingredients of drugs, to prove the quality of the drugs and to create technology. Help drug companies to do good research and development, quality control and promotion. Hotline: 13524733472 

Introduction: PL humanized mice, is through the transplantation of human hu-CD34+ stem cells into NOG mice, resulting in the human immune system in NOG mice to obtain reconstruction and obtain the human immune system.

Characteristics:

1. Human lymphocytes (hCD3+ CD4+ CD8+ cells) in the blood were increasing after 12 weeks.
2. The ratio of human lymphocytes (hCD45+ cells) in the blood to cells in the peripheral blood gradually increases, reaching more than 15% after 16 weeks.
3.PL mice can be used to evaluate the inhibitory effects of developing novel tumor immunizations including PD-1 antibodies, bispecific antibodies, CAR-T, and lysovirus biologics on the growth of subcutaneous grafted tumor models in NZG humanized mice.
