Identification of antigen epitopes with MAbs 7D4 and 2-5C-6F. (A) Schematic diagrams of all peptides (not drawn to scale) used in the peptide-scanning method. (a) Three overlapping peptides spanning the VP2 aa sequences. (b) Identification of the antigen epitope with MAb 7D4. (c) Identification of the antigen epitope with the MAb 2-5C-6F. (B) Recognition of the minimal epitope with 2-5C-6F by Western blotting. Lane 1 corresponds to the epitope of aa 317-336; 2, aa 318-336; 3, aa 319-336, 4 corresponds to aa 317-336; 5, aa 317-335; M, marker. (C) Recognition of the minimal epitope with MAb 7D4 by Western blotting. 1, aa 183-196; 2, aa 184-196; 3, aa 185-196; 4, aa 183-193, 5, aa 183-192, 6, aa 183-191; 7, aa 183-190; M, marker.
