Fig. 2From: Identification of novel serological agents for porcine deltacoronavirus infection based on the immunogenic accessory protein NS6 WB analysis of serum samples from pigs with or without PDCoV infection (PDCoV-positive or -negative sera). a Detection of serum anti-S1 or anti-NS6 IgG antibody in PDCoV-infected pigs using purified recombinant PDCoV S1 (lane 1), NS6 (lane 1) and PEDV S1 (lane 2; as a negative control) protein as the antigens. M: protein marker. Red arrows indicate the target protein bands. b Serum anti-S1 or anti-NS6 IgG antibody was undetectable in PDCoV-negative pigs. No target bands were displayedBack to article page
