1 The antigenic protein tissue transglutaminase was chemically modified, introducing disulfide groups through different moieties of the molecule (amine, carboxylic, and hydroxyl groups), self-assembled on gold surfaces, and used for the detection of IgA and IgG autoantibodies. Amines transglutaminase 2 Homo sapiens
2 The modified proteins were evaluated using enzyme-linked immunosorbent assay and surface plasmon resonance, which showed that only introduction of the disulfide groups through amine moieties in the tissue transglutaminase preserved its antigenic properties. Amines transglutaminase 2 Homo sapiens
