The country's first genetically modified chicken industry development company appeared in Shanghai

Introduction: as the transgenic chicken technology in the international animal transgenic frontier field, it has entered the stage of industrial development in China The reporter learned from the relevant government departments of Shanghai today that the first genetically modified chicken industry development company in China has appeared in Shanghai Shanghai Fudan Xinyang Biotechnology Co., Ltd., established by Shanghai Fudan University venture capital fund, Fudan University scientists and Shanghai Xinyang breeding stock farm with a joint investment of 2 million yuan, has taken the lead in developing stable technology for expressing foreign genes through egg white in China According to technical experts, the main achievements of this international level of transgenic chicken technology are: the construction of expression vector capable of expressing foreign genes in egg white; the establishment of effective transgenic technology, with the transgenic efficiency between 30% and 70%; the detection of the foreign gene "human leptin" in the egg white produced by more than 20% of transgenic chickens Protein ", the highest expression level of which is 10-30 mg / L egg white Such a high content has never been seen in China Professor Huang Weida, the chief scientist of the technology development research group and director of Biochemistry Department of Fudan University School of life sciences, said that with stable technology, we can smoothly enter the stage of industrial development He pointed out several possibilities for industrial development: first, to improve the quality of chicken germplasm, to cultivate a transgenic chicken strain with high growth rate, antiviral and low cholesterol egg production; second, to use egg white as a bioreactor to produce 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 Scientists say they are confident that they will bring the first batch of industrialization results to the market within two years At present, the development funds are not enough It is estimated that before the first batch of industrialization results are launched, 1 million to 2 million yuan is needed Scientists hope that through the press reports, more venture capital will enter the industrialization project Previously, a venture capital fund in Singapore and Fudan Morgan fund have shown interest in this project Due to the advantages of poultry in passage time and experimental cost, scientists engaged in the research of animal transgenic technology around the world have focused their attention from cattle and sheep to chickens In the past five years, there have been at least nine companies engaged in the industrialization of transgenic chicken in the world However, the development time of transgenic cattle technology is far earlier than that of chicken, and there are only more than 10 industrialized companies (author:) share to feed Weibo share to:
