Figure 5From: Development and validation of an ELISA using a protein encoded by ORF2 antigenic domain of porcine circovirus type 2ELISA using GST as a reference for evaluation of non-specific binding. Twenty serum samples including 10 positive sera (A) and 10 negative sera (B) were used. Each serum sample was run in quadruplicate, two on GST-ORF2-E antigen and two on GST antigen wells. Positive and negative control sera were induced in every plate.Back to article page
