Fig. 3From: Neutralizing antibodies against porcine epidemic diarrhea virus block virus attachment and internalizationDetection 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 shownBack to article page
