China’s National Institute of Metrology (NIM) develops monoclonal antibody reference material for COVID-19, and antibody and nucleic acid test kits from China are already being exported
Since the outbreak of the epidemic, immunoassays based on IgM antibody and IgG antibody of the COVID-19 patients have become an important supplement to nucleic acid-based detection.
Two new antibody reference materials developed by the NIM were now approvaed as national reference materials by the State Administration for Market Regulation.
As of March 16, a total of 11 nucleic acid detection reagents and eight antibody detection reagents for the COVID-19 were approved in China. According to a report by Japan’s Nikkei Biotech, some test kits developed by Tsinghua University, Sichuan University, Xiamen University, Xiamen University of Technology and Chongqing Medical University have already received CE certification and are exported to more than 10 countries, including Italy, the United Kingdom and the Netherlands.
