Amplicons obtained with the primers VP1F and VP1R that amplify a 498-bp fragment of the VP1 region of HAV (Lanes 1 and 2), and amplicons obtained with the primers NH2 and VP3-1431B that amplify a 455-bp fragment of the VP3 region of HAV (Lanes 3 and 4). Lanes N, negative controls. Lanes L, 100 bp DNA ladder (Promega).
