Seasonal Influenza Vaccine Antigens

In February and September of each year, the World Health Organization (WHO) convenes with its network of advisors to decide on flu vaccine formulations for the northern and southern hemispheres, respectively. To support ongoing vaccine reformulation programmes, The Native Antigen Company develops season-specific antigens to support vaccine and diagnostic manufacturers.

Our Antigens

At The Native Antigen Company, we are committed to advancing vaccine research and development. We proudly offer Haemagglutinin (HA) and Neuraminidase (NA) antigens for WHO-recommended egg-based and recombinant vaccine strains for Seasonal Influenza. Available in bulk quantities, antigens can be used in various applications, including immunoassay development and as immunogens. Why Choose Our Antigens?

Proprietary VirtuE™ HEK293 Expression System: Our antigens exhibit native-like glycosylation and folding, ensuring high-quality and reliable results.
Stabilized Trimeric Conformation: Featuring C-terminal T4 fold on domains, our Haemagglutinin antigens present more native-like conformational epitopes.

We are keen to undertake the production of novel strains/mutants of Influenza HA & NA as a bespoke service, including in-vivo biotinylated antigens. Contact us at nac.contact@lgcgroup.com to discuss your project now!
