Abstract PO-045: Multiplex analysis of coronavirus and influenza antibodies using the ZIVA multiplex platform

Abstract Detection of antibodies to upper respiratory pathogens is critical to surveillance, assessment of the immune status of individuals, vaccine development, and basic biology. The urgent need for antibody detection tools has proven particularly acute in the COVID-19 era. We have used Arrayed Imaging Reflectometry (AIR™), a label-free protein microarray technology that relies on the target binding-induced perturbation of an antireflective coating on the surface of a silicon chip, to create a multiplex antibody detection array. ZIVA is a new multiplex protein detection platform that leverages AIR™ technology. We have used ZIVA technology to develop an acute respiratory virus panel capable of detecting the presence of antibodies specific for coronavirus and influenza including, but not limited to, detection of antibodies to SARS-CoV-2, SARS-CoV-1, MERS, three circulating coronavirus strains (HKU1, 229E, OC43), and multiple strains of influenza. We find that the array is readily able to distinguish uninfected from convalescent COVID-19 subjects and provides quantitative information about total IgG, as well as IgG- and IgM-specific responses. Samples may also be evaluated with ZIVA cytokine assays to monitor the cytokine storm in conjunction with viral antibody response.
