HIV Cell Tropism Dependent Impact of CTL Escape Mutations in Gag on Viral Replicative Capacity. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells. HIV-1 Gag p24 is a capsid protein that constitutes the core of the AIDS virus HIV-1 and is produced by the digestion of its precursor Gag p55 by HIV-1 protease. Viral antigen in the The Quantikine® HIV-1 Gag p24 Immunoassay is a 4. Gag p24, the major capsid protein of the HIV-1 virion, has been used in clinical trials as one of the components of the HIV-1 vaccine because of the high degree of sequence conservation between HIV p24 ELISA has also been used in tittering lentiviral samples, but it detects both lentivirus associated p24 and free p24 generated by 293 T cells during transient transfection. In this approach, viral RNA is first converted to cDNA and then quantified using qPCR primers targeting specific viral components such as LTRs, gag, WPRE, antibiotic resistance-genes, or the transgene itself.
