HIV reservoir quantification by five-target multiplex droplet digital PCR

Abstract

Summary: Most latent human immunodeficiency virus (HIV) proviruses are defective and cannot produce infectious virions. Thus, the number of HIV proviruses with intact genomes is a relevant clinical parameter to assess therapies for HIV cure. We describe high-molecular-weight DNA isolation, followed by restriction enzyme fragmentation that limits cutting within the HIV genome. Multiplexed droplet digital PCR quantifies five targets spanning the HIV genome to estimate potentially intact proviral copies. A reference assay counts the number of T lymphocytes and assesses the level of DNA shearing.For complete details on the use and execution of this protocol, please refer to Levy et al. (2021).
