About Anti-gp120 (HIV-1/Clade B) Rabbit Polyclonal Antibody

The HIV-1 envelope glycoprotein gp120 is the exterior subunit of the viral Env complex and is responsible for the initial attachment of the virus to susceptible host cells through binding to the CD4 receptor and the chemokine co-receptors CCR5 or CXCR4. As the major surface antigen of HIV-1, gp120 contains numerous neutralizing epitopes and is the principal target of host antibody responses, therapeutic antibodies, and vaccine development. Because gp120 is essential for viral entry and immune recognition, antibodies against gp120 are widely used for studies of HIV pathogenesis, viral entry, recombinant protein characterization, and immunological research.

eEnzyme's Anti-gp120 (HIV-1/Clade B) Rabbit Polyclonal Antibody is generated by in vivo genetic immunization using the HIV-1 Clade B gp120 antigen, producing high-affinity antibodies that recognize the native conformation of the viral envelope glycoprotein. This immunization strategy promotes immune responses against correctly folded and naturally glycosylated gp120, resulting in excellent recognition of native viral envelope proteins. The antibody specifically reacts with HIV-1 Clade B gp120 and is suitable for Western blotting, ELISA, immunofluorescence (IF), immunocytochemistry (ICC), immunoprecipitation (IP), and other immunological assays. It provides a valuable reagent for HIV research, recombinant protein characterization, vaccine development, and diagnostic assay development.

Biological Significance of HIV-1 gp120

HIV-1 gp120 plays an indispensable role in viral infection by mediating attachment to CD4 and subsequent interaction with CCR5 or CXCR4, triggering conformational changes that activate gp41-mediated membrane fusion. As the most accessible viral antigen on the HIV surface, gp120 is the primary target of neutralizing antibodies elicited during infection and vaccination. It also exhibits extensive glycosylation and antigenic variability, allowing HIV-1 to evade host immune responses while maintaining receptor-binding function. Consequently, gp120 remains one of the most intensively studied HIV proteins for vaccine design, therapeutic antibody discovery, antiviral development, and structural biology.

The Anti-gp120 (HIV-1/Clade B) Rabbit Polyclonal Antibody provides a robust research tool for detecting native and recombinant gp120, monitoring envelope protein expression, characterizing vaccine antigens, and investigating HIV-host interactions. Its high affinity and recognition of conformational epitopes make it well suited for HIV immunology, virology, recombinant protein production, and translational infectious disease research.
