Next, we used immunofluorescent staining with SARS-2-N-specific primary antibodies and SARS-2-S2-specific primary antibodies against the S2-domain of the S-protein to analyze the expression of the SARS-CoV-2 proteins on the cell surface as well as the trafficking upon MVA-N or MVA-ST/N infection in Vero cells (Figure 1E). The gene discussed is PROS1; the disease is infection.
