VaxArray® for Coronavirus

Measure Antigen or Antibody With One Platform

VaxArray reagent kits for spike protein quantification and multiplexed serological assay

Accelerate coronavirus vaccine characterization using the VaxArray Coronavirus Spike Protein Assay kit to rapidly quantify functional spike protein in protein-based vaccines or as a functional potency test for nucleic acid vaccines. The Coronavirus SeroAssay can be used to efficiently quantify the humoral immune response to coronavirus vaccines, with immunogenicity against all human-relevant coronaviruses available from a single test.
