Figure 2From: Production and purification of VP2 protein of porcine parvovirus expressed in an insect-baculovirus cell systemWestern blot analysis of 6-His-tagged recombinant PPV VP2 protein expressed at different times after insect cells were infection with baculovirus. lane 1, the protein expressed in insect cells challenged with negative baculovirus; lanes 2 to 6, the protein expressed 1 to 5 days after insect cells were challenged with recombinant baculovirus; M, prestained protein ladder. The first antibody is PPV-positive pig sera, the second antibody is horseradish peroxidase-conjugated rabbit anti-pig antibody.Back to article page
