Figure 4From: Interactions of SARS Coronavirus Nucleocapsid Protein with the host cell proteasome subunit p42Western blot analysis of the interaction between p42-GST fusion protein and SARS-CoV NP in vitro. Bead + lysis buffer + NP (lane 1), bead + lysis buffer (lane 2), bead + GST lysate + NP (lane 3), bead + GST lysate (lane 4). Molecular weight markers (lane 5). SARS-CoV NP-SNP22b (positive control; lane 6), bead + p42-GST lysate (lane 7), bead + p42-GST lysate + NP (lane 8), p42-GST fusion protein bacterial lysate (lane 9). The position of SARS-CoV NP is indicated by an arrow.Back to article page
