About Epstein-Barr Virus (EBV) gH/gp42 Complex Recombinant Protein

Epstein-Barr virus (EBV) is an enveloped double-stranded DNA virus belonging to the genus Lymphocryptovirus in the family Herpesviridae. The gH/gL/gp42 complex is a key viral entry complex required for infection of B lymphocytes. In this complex, gp42 binds HLA class II molecules on B cells, while gH/gL cooperates with the viral fusion protein gB to trigger membrane fusion and viral entry. Because the gH/gL/gp42 complex is essential for EBV B-cell tropism and is a major target of neutralizing antibodies, it has become an important antigen for studies of viral entry, vaccine development, and therapeutic antibody discovery.

eEnzyme's EBV gH/gp42 Complex Recombinant Protein is produced for research use and is suitable for antibody screening, receptor-binding studies, ELISA development, Western blotting, epitope mapping, structural characterization, and EBV vaccine research. This recombinant protein provides a valuable reagent for investigating EBV-host interactions, B-cell entry mechanisms, immune responses, and antiviral therapeutic development.

Applications

Biological Significance of the EBV gH/gp42 Complex

The gH/gL/gp42 complex is indispensable for EBV infection of B lymphocytes. By engaging HLA class II on B cells, gp42 activates the gH/gL-gB fusion machinery, enabling viral membrane fusion and entry. This complex plays a central role in determining EBV cell tropism and contains important neutralizing epitopes recognized by protective antibodies. As a result, the EBV gH/gp42 Complex Recombinant Protein is a valuable research tool for studies of EBV pathogenesis, receptor interactions, vaccine design, and therapeutic antibody development.
