VaxArray® Influenza Seasonal NA Potency Test
Rapid Verification and Quantification of Neuraminidase in Influenza Vaccines (Human and Animal)
The VaxArray Influenza Seasonal NA Potency test is a multiplexed immunoassay specific for seasonal NA subtypes, N1, N2 and B-NA. The test relies on broadly reactive yet subtype specific monoclonal antibodies in a microarray format. This innovative multiplexed system enables simultaneous analysis of all neuraminidase antigens within multivalent vaccines, significantly reducing cost and testing time. Excellent correlation with enzymatic activity has been established and the VaxArray NA test can be used as an alternative to the semi-quantitative enzymatic activity assays to verify the presence of immunogenic NA in seasonal influenza vaccines. The VaxArray NA reagent kit can also be used to quantify NA in flu vaccines when paired with appropriate calibration antigens.
