HIV-1 Full-length Reporter Infectious Clone

 

The generation of infectious clones is essential for HIV research. These clones allow researchers to replicate the virus's behavior and investigate its pathogenesis, viral replication process, and host immune responses within a controlled lab setting.

The HIV-1 full-length reporter infectious clone, CCR5-tropic pNL4.3-ADA-GFP-IRES-NEF (HRP-20367), is now available through BEI Resources. This clone is based on the HIV-1 molecular clone pNL4-3 (ARP-114) and includes the GFP-IRES cassette inserted in-frame before the nef gene. The construct encodes all HIV-1 viral proteins, including the CCR5-tropic AdA Env, and co-expresses Nef and GFP from a single bicistronic RNA.1

The virus produced from this construct can infect various cell types, such as CD4+ T lymphocytes, monocyte-derived macrophages, primary fetal microglia, and monocyte-derived microglia. Infected cells show active viral transcription, leading to GFP expression.2,3,4 These cells can be identified using flow cytometry or microscopy, allowing for cell sorting to further characterize the infected cell populations.1
