The dynamic workflow of Alto™ digital SPR for Influenza vaccine development

Overview

Rapid changes in influenza antiviral target proteins due to antigenic drift result in the cloaking of the influenza virus from the immune system of vaccinated hosts. Hence, annual formulation updates for influenza vaccines and related antibody therapies are required to preserve immune recognition against different influenza subtypes. Rapid development and thorough characterization of antibody vaccine candidates for influenza viral antigens are essential for treating and preventing potential outbreaks.

Here, Nicoya’s Alto™ digital SPR is used across multiple stages of development including crude library screening, quantitation in serum, epitope binning and kinetics to characterize antibody candidates against Influenza A H5N1 Hemagglutinin (HA).

Capture screening heatmaps showing the expected and observed outcomes for the antibodies tested against the Influenza A H5N1 HA and H3N2 HA antigens. Interactions were labeled as ‘bind’ if the analyte response was ≥ 40 RU.
