Detection of the homozygous and heterozygous HIV-1 particles at single-RNA-molecule sensitivity. All particles were produced by cells transfected with Bgl-mCherry and MS2-YFP. (A) Images of particles generated from coexpression of 2 HIV-1 genomes, 1 containing MS2 stem-loops and the other containing BglG stem-loops. Both genomes contained GCGCGC in the dimerization initialization signal (DIS). (B) Particles generated by coexpression of an HIV-1 genome with GCGCGC in the DIS and an HIV-1 genome with GTGCAC in the DIS. (C) Particles generated by coexpression of an HIV-1 genome with GGGGGG in the DIS and CCCCCC in the DIS. Abbreviations are the same as in Fig. 2.
