Figure 4From: Expression of hemagglutinin protein from the avian influenza virus H5N1 in a baculovirus/insect cell system significantly enhanced by suspension cultureSDS-PAGE and immunoblot analysis of supernatant (lane 1 and 3) and pellet (lane 2 and 4) after lysis of recombinant baculovirus infected Sf9 cell with lysis buffer containing 1% NP-40. Values on the left indicate molecular weights of the maker protein (LaneM).Back to article page
