Detection of their antigenicity for mAbs by IFA. The different mAb used for the assay are indicated at the top. Recombinant protein (SP, N, M and ORF3) produced by Baculovirus expression is shown on the below. SP is the S1 and partly S2 gene fragment (encoding 1-954aa). The experiment was repeated two times, and representative images are shown
