Antibody Immobilization on Solid Surfaces: Methods and Applications

The correct immobilization of the antibody component is one of the most critical steps in the development of immunoassays, immunosensors and immunochromatography matrices. Advances in hybridoma technology and protein engineering have allowed traditional limitations of polyreactivity of antibody preparations, poor device stability and random orientation of binding pockets to be largely overcome, resulting in stable, sensitive, highly specific and enormously diverse immunoplatforms with applications in diagnostics, environmental monitoring, and food and public safety. In this Chapter we introduce antibody structure and antibody-derived fragments, describe the most common methods of their immobilization and discuss ‘traditional’ applications of immobilized antibodies such as enzyme immunoassays and immunoaffinity chromatography, as well as exciting emerging uses in immunosensors, microarrays and nanomedicine.
