Anti-Hepatitis C Virus NS4 Antibody [7B7/5G9]

This unconjugated mouse IgG1 monoclonal antibody targets the NS4 non-structural protein of the human Hepatitis C Virus and is offered by Antibodies.com as a lyophilised 100 µg preparation suitable for both ELISA and Western blot workflows. Clone 7B7/5G9 binds the NS4 antigen with specificity for HCV, supporting research into viral polyprotein processing, replication complex assembly, and the host response to infection.

The reagent is supplied without a fluorophore or enzyme label, so investigators can conjugate it directly with HRP, biotin, or a fluorescent tag according to the assay format. Reconstitution in sterile buffer restores the antibody to working concentration, and aliquots can be frozen for repeated use across longitudinal studies. Because the antibody is monoclonal, lot-to-lot variability is minimized, which matters when comparing viral antigen expression across many samples or screening antiviral compounds.

Typical applications include detection of NS4 in transfected cell lysates, recombinant protein characterization, and supporting in vitro studies of HCV genotype reactivity. The unconjugated format allows the antibody to be integrated into diverse immunoassay designs, including those requiring labeled secondary detection or direct conjugation to a solid phase.
