Adaptations of a Competitive Enzyme-Linked Immunosorbent Assays for the Detection of Antibodies to Influenza A Virus in Horse Sera for Use in Wild Aquatic Birds

We applied a competitive enzyme-linked immunosorbent assay for the detection of antibodies for influenza A in equine sera to their detection in sera from wild aquatic birds. Suboptimal results were obtained for the optical density (OD) of the monoclonal antibody (MAb) control and reproducibility between duplicate analyses in the initial assessment. It was therefore necessary to modify the assay to deliver increased reliability and reproducibility while maintaining adequate sensitivity. We optimized reagent concentrations to obtain optimal OD values (close to 2) for the monoclonal antibody control and used 2, 2'-Azino-bis: 3-Benzthiazoline-6-Sulphonic Acid as an alternative chromogen to poten..
