Fig. 5From: Molecular mechanisms by which HERV-K Gag interferes with HIV-1 Gag assembly and particle infectivityHERV-K Gag reduces release efficiency of HIV-1 at a stage prior to particle pinching-off. HeLa cells were cotransfected with HIV-1/YP(−) and indicated pCMV plasmids and pCRVI plasmids. The amount of p24 in the virus pellet was measured by ELISABack to article page
