About SIVmac239 Nef Recombinant Protein

Simian Immunodeficiency Virus (SIV) is a lentivirus that naturally infects non-human primates and serves as the principal animal model for HIV/AIDS research. The Nef (Negative Factor) protein is an accessory protein expressed early during infection and is a major determinant of viral pathogenesis. Although Nef is not essential for viral replication in vitro, it enhances viral infectivity and promotes immune evasion by downregulating CD4, MHC class I, and other host cell surface proteins, while modulating T-cell signaling and intracellular trafficking pathways. The SIVmac239 isolate is one of the best-characterized molecular clones and is widely used in rhesus macaque models of HIV infection.

eEnzyme's SIVmac239 Nef Recombinant Protein is produced for research use and is suitable for studies of SIV pathogenesis, host-virus interactions, antibody generation, ELISA development, Western blotting, epitope mapping, T-cell immune response analysis, and non-human primate AIDS research. This recombinant protein provides a valuable reagent for investigating Nef-mediated immune modulation and supporting HIV/SIV vaccine and therapeutic development.

Biological Significance of SIVmac239 Nef

SIVmac239 Nef is a multifunctional accessory protein that plays a central role in viral persistence and disease progression in non-human primate models. By modulating host immune responses and cellular signaling pathways, Nef enhances viral fitness and promotes immune escape. Because of its conserved biological functions and critical role in SIV pathogenesis, SIVmac239 Nef is widely used to investigate lentiviral immune evasion, evaluate vaccine-induced immune responses, and study mechanisms of HIV/AIDS pathogenesis in rhesus macaque models. The SIVmac239 Nef Recombinant Protein provides a valuable research tool for basic virology, immunology, and translational HIV/SIV research.
