摘要: National Resource Center (NRLARC) for Rodent Laboratory Animal was established in 1998, ratified by State Commission of Science and Technology. Subordinated to laboratory animal center For National Institute for the Control of Pharmaceutical and Biological Products. The major aims are: importing, collecting and conserving the variety of LA and strain of LA, studying new LA protection techniques, developing the new strain and varieties of LA and supplying the standard breeding of LA to several client both at home and abroad. Since its founding, the Center has made twice announcement to the whole nation of supplying the breeding animallist. On the basis of around statistics from 1998-2002, the Center has supplied about 15 thousand SPF LA adult mice and rats to about 50 units in over 20 provinces. Through the service these years, the Center has played an important role in improving the quality of LA in China. At present the Center keeps about 20 strains such as rat, mouse, Guinea pig and rabbit. Now it is continuing recommending the very need breeding of LA from home and abroad to meet the demand of the development in life science. The Center has strictly control the quality of LA and has regular check up to ensure to supply the qualified breeding of LA to the clients,meanwhile, we persist in technique innovation as we have a strong professional team who has made quite a few national level key scientific projects of the Ninth Five year Plan and the Tenth Five year Plan, making great contributions to the work of animal protection and breeding, as well as resource conservation. Our major researches are:(1)the research on embryo frozen;(2)the establishment of embryo bank;(3)standardization of KM mouse;(4)the establishment of animal resource online system;(5)gnotobiotic rabbit.
