Figure 4From: Membrane topology analysis of HIV-1 envelope glycoprotein gp41Topological analysis of gp41 in 293FT cells. Images of the cells stained with the membrane impermeable ligand, Alexa Fluor 488 (AF488), for HaloTag. The staining and image capturing were done at 44 h post transfection. Mock, mock DNA transfection. The names of expression vectors are shown. The bar indicates 30 μm.Back to article page
