Pre-Validated Assays for Faster Time to Market
The World Health Organization releases influenza strain recommendations semiannually for inclusion in Northern and Southern Hemisphere vaccine formulations. Influenza strains changes often require updates to currently used analytical methods, increasing the analytical burden on influenza vaccine developers and manufacturers.
InDevR does the hard part for you by ensuring reactivity to World Health Organization-recommended strains, eliminating months of analytical development time. Benefit from our growing portfolio of over 300+ subtype-specific influenza monoclonal antibodies for rapid product updates.

OmniFlu HA
A Versatile Multivalent Hemagglutinin Assay for Identity and Quantity of Seasonal Influenza Subtypes
Improve your time to market with pre-validated detection of hemagglutinin (HA) from influenza subtypes A/H1, A/H3, and B/Victoria and B/Yamagata lineages for every WHO-recommended seasonal strain. The OmniFlu HA Kit is an off-the-shelf, validated solution for seasonal influenza vaccine manufacturers, providing production platform flexibility for hemagglutinin quantification and detection. The novel design of the OmniFlu HA enables comprehensive multivalent detection of influenza HA from a wide range of expression systems, including egg, cell, recombinant, and HA proteins expressed after mRNA-transfection.
Seasonal strain updates increase the time to market for influenza vaccine manufacturers due to updates to analytical methods. InDevR’s OmniFlu HA reduces the validation burden by confirming reactivity with every strain update. In the example shown here, OmniFlu HA was reactive and specific for each subtype over vaccine relevant concentrations in a quadrivalent egg-based vaccine from the Northern Hemisphere 2023-2024 season.
There is a need to measure intact, expressed HA and NA from cells that are transfected with influenza mRNA vaccines. HEK293-expressed protein post-transfection with a quadrivalent mixture of influenza HA mRNA constructs was measured by OmniFlu HA Assay as a function of input mRNA concentration. Protein expression increased as a function of input mRNA concentration and, as expected, the different proteins exhibit different expression levels.
VaxArray Influenza Seasonal Neuraminidase Multivalent Assay
Neuraminidase (NA) identity testing is required for any vaccines expected to contain NA, and NA quantification is an area of active interest for future regulation of whole virus, split virus, or subunit influenza vaccines. Identity and quantification of influenza neuraminidase subtypes N1, N2, and B/NA have never been easier!
Reduce stress and delays in the seasonal strain update process with confidence that the VaxArray Influenza Seasonal NA Assay is confirmed reactivity for all WHO-recommended strains. The VaxArray Influenza Seasonal NA Multivalent Assay Kit is a powerful tool for rapid, multivalent detection of NA vaccine components with high specificity.
Vaccine manufacturers sought to confirm the presence of N1, N2, and B/NA in seasonal influenza vaccines. Analysis of a multivalent influenza vaccine by the VaxArray Influenza Seasonal NA Assay resulted in specific signal for identity testing. This assay is also accurate for multiplexed quantification of NA over a vaccine relevant concentration range.
VaxArray Influenza Pandemic Hemagglutinin Multivalent Assay
Streamline the development of pandemic influenza vaccines with the VaxArray Influenza Pandemic HA Assay Kit that targets H5, H7, and H9 subtypes. Each test contains 5 capture antibodies that target the most prominent and potentially pandemic A/H5 viruses, 2 capture antibodies for broad reactivity with H7, and 2 antibodies recognizing H9. This assay has been verified reactive with an array of strains and production methods from the following subtypes:
- H5N1, H5N8, H5N6, and H5N2
- H7N2, H7N3, H7N7, H7N9
- H9N2
