ABSTRACT
A system proposed for measurement of mutational risk consists in detection of hemoglobin mutations expressed in erythrocytes. For this detection the production of antibodies specific for Hb variants is essential. Recently we reported a sensitive solid-phase EIA for the production and selection of polyclonal and monoclonal antibodies specific for hemoglobin determinants. An important characteristic of this EIA was the coating of water-insoluble proteins to polystyrene microtiter plates. Here we report that with this system, insoluble protein fragments and small peptides may also be covalently coated to a polystyrene surface. Coating is independent of the length of the peptides. This allows direct, non-competitive titration of the antibody response to small peptides and avoids the drawbacks of competitive assay.
