Novel Assays for Measurement of Total Cell-Associated HIV-1 DNA and RNA.

ABSTRACT: Although a number of PCR-based quantitative assays for measuring HIV-1 persistence during suppressive antiretroviral therapy (ART) have been reported, a simple, sensitive, reproducible method is needed for application to large clinical trials. We developed novel quantitative PCR assays for cell-associated (CA) HIV-1 DNA and RNA, targeting a highly conserved region in HIV-1pol, with sensitivities of 3 to 5 copies/1 million cells. We evaluated the performance characteristics of the assays using peripheral blood mononuclear cells (PBMCs) from 5 viremic patients and 20 patients receiving effective ART. Total and resting CD4(+)T cells were isolated from a subset of patients and tested for comparison with PBMCs. The estimated standard deviations including interassay variability and intra-assay v
