SinoBiological社 Antibodies for Influenza Antigen Test

Influenza viral nucleoprotein (NP) is a structural protein that plays a critical role in virus replication and host adaptation. Antibodies targeting NP proteins are commonly used for immunodetection of influenza viruses in various assays, including ELISA, lateral flow assay (LFA), and direct fluorescent antibody tests. These assays can be used in both research and clinical diagnostics. Due to the high frequency of antigenic drift or shift among different influenza strains, broad-spectrum influenza antibodies are particularly desired for flu diagnostics.
Sino Biological has identified six Pan antibody pairs against the NP protein of Influenza A and Influenza B, respectively. These matched pairs have been validated in the sandwich ELISA assay with high sensitivity (pg level). They also demonstrate broad reactivity against a large cohort of flu strains.

Broad Spectrum and High Specificity
These antibody pairs can detect a broad spectrum of strains within the target subtype, without any cross-reactivity with the other subtypes.
