New discovery of transgenic sheep

Introduction: genetic drugs are extracted from the milk of genetically modified sheep in Beijing Shunyi three high tech agricultural demonstration area, the breeding base of genetically modified sheep in China The drug output of a sheep is equivalent to that of a natural genetic drug manufacturer This is another new discovery after the successful cultivation of genetically modified sheep in China It is understood that China's first transgenic sheep with human (maaat) gene was successfully cultivated by Beijing xinglvyuan three high Biotechnology Center, which settled in the demonstration area last June, with a success rate of 13.79%, ranking the world's leading level At present, it is found that the milk production rate of the transgenic sheep is very high, with 10 months of milk production period in a year, and the annual output is as high as 2000 kg Compared with the traditional medicine, the gene medicine extracted from its milk has obvious advantages For example, the production of coagulation factor VIII, a specific drug for the treatment of hemophilia A, is very representative The annual demand for this drug is 120g If the 120g coagulation factor is extracted from plasma by traditional production method, it will take about 5 million blood donors to provide plasma to meet the market However, the milk production of a sheep is more than 800kg, and 250mg coagulation factor is extracted per kg Factor VIII, then, one such transgenic sheep can meet the needs, so it can be called "gene drug manufacturer" (author:) share to feed Weibo share to:
