HIV-1 gp120 Protein (His)

HIV-1 gp120 is an envelope glycoprotein derived from the surface subunit of the HIV-1 Env protein. It plays a critical role in viral entry by binding to the CD4 receptor and CCR5/CXCR4 co-receptors on host cells. Recombinant gp120 is commonly used in studies of HIV pathogenesis, neutralizing antibody screening, vaccine development, and receptor-ligand interaction assays.
