The ongoing COVID-19 pandemic has sickened over 380,000 people worldwide. There is an urgent need to increase the current diagnostic capacity. Compared with the commonly-used PCR testing, serological assay-based diagnostic method is much easier and faster to perform. To support the development of immunodiagnostic assay, Sino Biological has developed a comprehensive collection of antigens and antibodies for SARS-CoV-2. These reagents have already been used to manufacture NMPA-approved diagnostic kits in China.

Serological study can also be performed in HTP fashion. In collaboration with Nanommune, Sino Biological has developed the coronavirus antigen array. This array simultaneously probes 67 antigens from all seven known coronaviruses, along with several types of adenovirus, RSV, MPV, parainfluenza and Influenza viruses. The test can reveal IgG and IgA seroreactivities to different viruses. This assay may be useful to determine the seroprevalence of the SARS-CoV-2.
