China's transgenic chicken technology enters the forefront of the world

Introduction: Xinhua news agency, relevant government departments in Shanghai recently revealed that with the development of transgenic chicken technology in the international animal transgenic frontier field, the first transgenic chicken industry development company in China has emerged in Shanghai, taking the lead in developing the technology of exogenous gene expression through egg white     According to technical experts, the main achievements of this international level of transgenic chicken technology are: the construction of an expression vector capable of expressing foreign genes in the egg white; the establishment of an effective transgenic technology, with the transgenic efficiency between 30% and 70%; the detection of the foreign gene "human leptin protein" in the egg white produced by more than 20% of transgenic chickens, and the detection of the foreign gene "human leptin protein" The highest expression level was 10 to 30 mg / L of egg white If the content is high, it has never been in China Gj2 Professor Huang Weida, chief scientist of this technology development research group and director of Biochemistry Department of Fudan University School of life sciences, said that after obtaining stable technology, there are several possibilities for industrial development: first, improving the quality of chicken, cultivating transgenic chicken strains with high growth rate, antiviral and low cholesterol egg production; second, using egg white as a bioreactor in egg white Production of protein polypeptides with medicinal value, such as human high density lipoprotein, human serum albumin and other cytokines, vaccines and antibodies In the market, there will be "nutritious eggs" and "healthy eggs" that are really effective in preventing cardiovascular disease and fighting cancer Relevant experts said that according to the national "safety management of agricultural genetically modified organisms", relevant technologies need to be evaluated for safety, and can only be put into production after obtaining the safety certificate GJ2 (author:) to feed Weibo to:
