InDevR Unveils Latest Version of Influenza Titer on Chip Product

By Pharma Tech Outlook | Friday, November 30, 2018

BOULDER, CO: InDevR, a developer of advanced life science instrumentation and assays for analysis of viruses and other microorganisms has come up with VaxArray Influenza potency assay, a new version of its Influenza Titer on Chip or Flu-ToC product.

The new product released by the company is an immunoassay for hemagglutinin (HA) that uses antibodies involving subtype-specific, broadly reactive monoclonal rupture antibodies. The product offers results in just two hours.  The flu researches and vaccine producers involved in vaccine research can now get all the information related to flu vaccine. Besides this, they can also gather information regarding samples of crude extracts through purification and concentration steps.

The improvements of the product includes longer reagent shelf-life, a semi-automation protocol for increased ease of use, less hands-on time, higher throughput and reduced assay time. In addition, VaxArray offers a streamlined automated data analysis package.

For influenza vaccines, typically HA quantification is performed using the single radial immunodiffusion assay (SRID). It is reliant on seasonal reference antisera and antigens as well as gels that must be prepared in-house. Subsequently, analysis can be inconsistent between laboratories and scientists. SRID is also a singleplex method known to have limited dynamic range. The VaxArray Influenza potency assay has been recognized by the US Department of Health and Human Services as a promising alternative to SRID.

"Time to market in the vaccine industry is critical. With VaxArray customers save valuable time with an off-the-shelf potency assay that allows them to assess HA concentration and stability within hours rather than days, even during the early stages of development," says Kathy Rowlen, Chief Executive Officer, InDevR. "We have re-branded Flu-ToC to better reflect the platform flexibility. While VaxArray Influenza is the first potency assay we've launched, the technology will be useful for other vaccines as well. Animal vaccines and vaccines against potential pandemic influenza viruses represent another great market opportunity for this product and we intend to pursue those applications next."
