Analysis of Early Human Immunodeficiency Virus Type 1 DNA Synthesis by Use of a New Sensitive Assay for Quantifying Integrated Provirus

Abstract

A novel Alu -long terminal repeat (LTR)-based real-time nested-PCR assay was developed to quantify integrated human immunodeficiency virus type 1 (HIV-1) DNA in infected cells with both accuracy and high sensitivity (six proviruses within 50,000 cell equivalents). Parallel assays for total HIV-1 DNA and two-LTR HIV-1 DNA circles allowed the synthesis and fate of the different HIV-1 DNA species to be monitored upon a single round of viral replication.
