Description
Subtype Specific Influenza Vaccine Quantification
Hemagglutinin, neuraminidase, or nucleoprotein quantification at any manufacturing process step. Quantitative, stability indicating measurements of vaccines can be difficult, time consuming, and inaccurate. VaxArray solves these issues by providing a rapid, multiplexed measure of influenza protein concentration using an immunoassay built into a microarray format. Specifically designed for analysis of seasonal and pandemic flu vaccines, VaxArray allows for simultaneous analysis of quadrivalent vaccine formulations even in crude, upstream matrices.
Benefits
- Fast and easy with <30 minutes hands-on time and 2 hour time to results
- 100x more sensitive than SRID, with demonstrated equivalence for monovalent and multivalent vaccines.
- Capture reagents are selected to be robust against antigenic drift.
- Available year-round, even prior to reference reagents availability.
- Subtype-specific, enabling quantification of monovalent, trivalent, or quadrivalent formulations.
- Stability-indicating immunoassay measures biologically relevant forms of HA, NA, and NP.
- Compatible with crude, purified, or adjuvanted samples, from any production method.
