InVivo now offers recombinant antigens for Corona virus / COVID-19 in vitro diagnostics.

Using transient gene expression in HEK cells, InVivo successfully produces different surface glycoprotein (S) variants. These include the SARS-CoV-2 Receptor Binding Domain (RBD) with C-terminal His-Tag, the S1 subdomain and the S2 subdomain with cleavable C-terminal His-Tag, and a soluble Spike protein. The proteins can be used for serological detection of COVID-19 antibodies in immunoassays, such as ELISA and Lateral Flow tests.

Further developments include stable CHO cell pools for larger quantities of antigens, as well as stable monoclonal CHO cell lines.
