Figure 1From: High prevalence of antibodies against polyomavirus WU, polyomavirus KI, and human bocavirus in German blood donors Confirmation of expression of recombinant proteins. Sf9 cells were infected with recombinant baculoviruses BacWUVP1, BacKIVP1, and BacBoVP2. Uninfected Sf9 cells served as negative control. After SDS-PAGE and immunoblot, proteins were visualised by staining with anti-V5 antibody. The expected protein sizes are ~46 kDa (WUPyV and KIPyV VP1) and ~66 kDa (HBoV VP2).Back to article page
