Disclose Formula for SARS-CoV-2 IgG/IgM

During the severe situation of the COVID-19, the company deeply reflected its sense of social responsibility. We publicly test the formula for other peer companies to make medical devices and reagents against COVID-19, so as to better estimate people's health. We will spend this difficult time with the whole society. This was also world’s first paper to disclose formula of SARS-CoV-2 IgG and IgM assays on CLIA platform, which helped IVD companies to launch their SARS-CoV-2 IgG and IgM assays on CLIA.
