Figure 5From: Engineering of papaya mosaic virus (PapMV) nanoparticles with a CTL epitope derived from influenza NPTrypsin digests of recombinant PapMV NP nanoparticles cross-linked with glutaraldehyde. PapMV NP-12 and PapMV NP-C either cross-linked with gluteraldehyde or not were submitted to a trypsin digest. The reaction was stopped by adding 10 μl of loading dye. Samples were heated for 10 minutes at 95°C prior to loading on an 8% SDS-PAGE.Back to article page
