Abstract: Low-cost disposable immunosensors were produced by covalent binding of Protein A or G on graphite-polystyrene screen-printed electrodes, and they were used in a fully automated flow injection analysis (FIA) system, allowing the kinetics of IgG binding to Protein A or G to be improved by forced convection. The displacement of rabbit IgG bound to Protein A or G by mouse IgG isotypes (IgG(1) or IgG(2a)) was studied. A FIA immunoassay of mouse IgG(2a) was performed at a Protein A-based immunosensor with a good sensibility (down to 0.02 µg ml-1) and a total assay time of 19 min. It was shown that the immunosensor combines the advantages of being reusable for more than 30 assay cycles in flow injection analysis, and disposable when necessary.
