The newly identified coronavirus, SARS-CoV-2 (2019-nCoV), has led to pneumonia (COVID-19) that sickened over 40,000 people in China. The medical community fears that this outbreak may be on its way to become a global pandemic in the near future, if not controlled soon.

To aid the efforts of developing vaccines and neutralizing antibodies against this virus, Sino Biological Inc. has developed a panel of recombinant antigens for this new coronavirus, including the N (nucleocapsid) protein, S protein, the S1 and S2 subunits of the S protein, and the RBD domain of the S proteins, and antibodies that recognize the S protein.
