Fig. 9. Sf9 cells co-infected with recombinant baculovirus containing Prob and Mt. Prob/Mt co-infected cells were double-stained with a polyclonal antibody anti-MAP2 (A), to visualize the expression of Prob, and the monoclonal antibody 46.1, to reveal the expression of Mt (D). Prob/Mt co-infected cells were also double-stained with the polyclonal antibody anti-MAP2 and a monoclonal antibody against -tubulin to visualize the formation of microtubules by Mt. Cells expressing Prob were double-stained with the polyclonal antibody anti-MAP2 and a monoclonal antibody against -tubulin to show that Prob does not induce the formation of microtubules in Sf9 cells.
