Lateral Flow Assay for Influenza & SARS-CoV-2 Viruses Detection

Let GeneTex support your assay development project with outstanding recombinant antibodies for influenza A and B nucleoproteins as well as for SARS-CoV-2 nucleocapsid. Request complimentary samples (up to 1 mg each) of these antibodies to study their performance in your assay platform. Offer is limited to end-users in North America only.

GeneTex is an internationally recognized antibody manufacturer with an established reputation for providing virology research reagents of the highest quality. We have developed a series of recombinant rabbit antibodies targeting the nucleoproteins of either influenza A or B, which recognize at least sixteen influenza A and nine influenza B strains, respectively. These monoclonal antibodies are available as matched pairs for lateral flow assay (Figure 1) and demonstrate superior sensitivity compared to other products on the market (Figure 2). In addition, GeneTex’s comprehensive SARS-CoV-2 catalog includes recombinant rabbit antibodies against the SARS-CoV-2 nucleocapsid protein (which will also recognize Omicron) (Figure 3). As with the influenza antibodies, antibody pairs validated to detect nucleocapsid in lateral flow assays have been identified (Table).
