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

The HIV-1 Gag (Group-specific antigen) polyprotein is one of the most abundant and highly conserved structural proteins of HIV-1 and is essential for viral assembly, budding, and maturation. During viral maturation, the p55 Gag precursor is cleaved by the viral protease into the mature structural proteins matrix (MA, p17), capsid (CA, p24), nucleocapsid (NC, p7), and p6, which together form the architecture of infectious virions. Because Gag is highly immunogenic and expressed at high levels during viral replication, it is widely used in studies of HIV biology, lentiviral vector production, vaccine development, and diagnostic assay development.

eEnzyme's Anti-Gag (HIV-1/Clade B) Rabbit Polyclonal Antibody is generated by in vivo genetic immunization using an in vivo expressed HIV-1 Clade B Gag protein as the immunogen, producing high-affinity antibodies that recognize native Gag proteins. This approach promotes immune responses against correctly folded antigens, providing excellent recognition of recombinant and native HIV-1 Gag proteins. The antibody specifically reacts with HIV-1 Clade B p55 Gag and processed Gag proteins, is immunogen affinity-purified, 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, lentiviral vector characterization, recombinant protein analysis, and vaccine development.

Biological Significance of HIV-1 Gag

The Gag polyprotein is the principal structural component driving HIV-1 particle assembly. Following synthesis, Gag targets the plasma membrane, recruits viral genomic RNA, and assembles into immature virus particles. During or shortly after budding, HIV-1 protease cleaves p55 Gag into the mature structural proteins p17 (matrix), p24 (capsid), p7 (nucleocapsid), and p6, a process that is essential for the formation of infectious virions. Because Gag is highly conserved among HIV-1 isolates and is abundantly expressed during infection, it remains one of the most important targets for studies of viral assembly, maturation, host immune responses, lentiviral vector manufacturing, and antiviral drug development. Antibodies recognizing Gag proteins are indispensable tools for monitoring virus production, characterizing recombinant Gag expression, evaluating vaccine candidates, and supporting HIV molecular virology research.
