Some HIV reverse transcription complexes contain p24CA protein. Hos cells that express CD4 and CCR5 were injected with Alexa–dUTP (red) and infected with GFP–Vpr-labeled YU strain of HIV (green) (MOI ∼10) for 4 h, fixed, and stained with p24CA antibody. (A) Perinuclear region of a cell with some nuclear incorporation of Alexa–dUTP. (B) Merged (left) and individual color images of a p24CA-negative RTC. Note the presence (top right) of a dUTP-negative, p24CA-positive particle. (C) Merged and individual images of p24CA-positive RTCs. (D) p24CA-positive and -negative RTCs associate with microtubules. Microtubules (blue) were stained in addition to p24CA, and images were collected in four color spectra. (E) Shows the same two RTCs without microtubules, and (F) shows the p24CA (blue) staining profile. Bars: (A) 5 μm; (B–F) 2 μm.
