VaxArray® Influenza Seasonal Hemagglutinin Potency Assay,Seasonal HA Assay for VaxArray Platform

axArray® Influenza Seasonal Hemagglutinin Potency Assay

Seasonal HA Assay for VaxArray Platform

VaxArray® is an immunoassay, imaging, and potency interpretation platform. When the VaxArray® Imaging system is paired with the Influenza Seasonal Hemagglutinin potency assay kit, it creates a semi-automated platform to rapidly perform singleplex and multiplex immunoassays for seasonal hemagglutinin quantification.  VaxArray Influenza can be used at any stage in the vaccine manufacturing process.  With its high specificity, accuracy and speed, potency determination for multiple strains can be obtained in less than 2 hours.  The assay is based on a “universal” panel of subtype-specific monoclonal antibodies printed in an array format.

  • Sample Preparation Time: Equivalent to SRID
  • Assay Time: Less than 2 hours compared to 24 hours for SRID
  • Data Analysis Time: Automated taking less than 5 minutes

Broad Applications

VaxArray® Influenza can be used to quantify HA protein in any influenza vaccine manufacturing or research method and in almost any medium, including crude extract, bulk drug substance, and finished vaccine product. It has been shown to work with split viruses, virus like particles, as well as recombinant HA.

The VaxArray® Influenza potency assay is currently being evaluated by the US Department of Health and Human Services as an alternative to single radial immunodiffusion (SRID, also SRD) for vaccine potency determination.
