Construction of the plasmids PVAX1-ORF2 and PVAX1-ORF2-C3d-P28.3 (a) Top: the ORF2 construct that was used as a vaccine insert; Bottom: the ORF2-C3d-P28.3 construct that was used as a vaccine insert. Linkers composed of two repeats of four glycines and a serine [(G4S)2] were fused at the junctures of ORF2 and C3d and between each C3d repeat. b Restriction digest of PVAX1-ORF2 and PVAX1-ORF2-C3d-P28.3. Lane 1: DL2000 marker; lane 2: PVAX1-ORF2 digested with Nhe I/Hind III; lane 3: PVAX1-ORF2-C3d-P28.3 digested with Nhe I/Hind III; lane 4: DL5000 marker
