17 new crown diagnostic reagents launched in Beijing
News from this newspaper (Reporter Yuan Lu) Recently, the State Food and Drug Administration approved 21 new crown antigen self-test reagent products, of which 6 products were produced by Beijing, ranking first in the country.
Behind the "acceleration" of Beijing's new crown virus antigen detection kit manufacturers, the Beijing Municipal Science and Technology Commission and the Zhongguancun Management Committee jointly established a technical platform to start scientific and technological research, and successively promoted the approval of 17 new crown pneumonia diagnostic reagents. .
The 6 newly approved COVID-19 antigen self-test reagent products are from Beijing Jinwofu Bioengineering Technology Co., Ltd., Beijing Huaketai Biotechnology Co., Ltd., Beijing Rejing Biotechnology Co., Ltd., and Wantai Biopharmaceutical Co., Ltd. , Lepu Diagnostic Technology Co., Ltd., Beijing Zhuocheng Huisheng Biotechnology Co., Ltd.
"At present, our production capacity basically meets the market demand in the production of new coronavirus antigen self-test reagents." Yesterday, at the media briefing on the approval of new coronavirus antigen detection reagents in Beijing, Yu Tao, Marketing Director of Wantai Bio, said that the company is currently in The single-day production capacity of Beijing's new crown antigen self-testing agent has climbed from 1 million to 1.5 million, and an automated reagent assembly line is used.
Since the outbreak of the new crown epidemic, Beijing has made use of its advantages in the biomedical industry to continue to help the global war against the epidemic.
The Municipal Science and Technology Commission and the Zhongguancun Administrative Committee quickly launched the layout of scientific and technological research, closely linked key links such as technology development, process verification, clinical verification, emergency approval, etc., and jointly established the "New Coronary Pneumonia Diagnostic Reagent Technology Platform for Scientific and Technological Research" in conjunction with testing, clinical institutions and key enterprises. ".
"By tracking the research and development of key enterprises, we have accelerated the ethical approval and clinical verification of clinical institutions, coordinated the development of standard products and quality control products by testing institutions and enterprises, and accelerated the development and launch of diagnostic reagents." Municipal Science and Technology Commission, Zhongguancun Management Du Xiaojing, deputy director of the medical department of the committee, introduced that as of March 30, the platform has promoted the approval of 17 new coronary pneumonia diagnostic reagents, covering three technical routes of nucleic acid, antibody and antigen.
The reporter learned that at present, there are three kinds of new crown antigen self-test reagents produced by Beijing enterprises, namely colloidal gold method, latex method, and fluorescent immunolayer analysis method. The new coronavirus can greatly shorten the waiting time.
Among them, the colloidal gold method and the latex method are both commonly used immunolabeling techniques. Colored colloidal gold or latex is used as the marker, which does not need to rely on instruments and is suitable for self-detection.
Among the first batch of new crown antigen detection reagent products approved for marketing, Beijing Huaketai's detection kit adopts the fluorescence immunolayer analysis method.
Huaketai Marketing Director Wang Lili told reporters that this detection method can be used with instruments to avoid manual interpretation errors and has higher sensitivity.
The new crown antigen self-testing agent developed by Beijing enterprises has also gone abroad to help the global fight against the epidemic.
Up to now, Beijing Rejing Bio’s new crown antigen has exported more than 700 million copies, and Wantai Bio’s new crown series detection reagents have been exported to more than 40 countries and regions, with a total of more than 100 million copies.
