Determination of Anti-?-Gliadin Antibodies in Serologic Tests for Coeliac Disease

Abstract

The comparison of results using purified gliadins shows that omega-gliadins present a differential reactivity that has not previously been documented. Results using omega-gliadins isolated by either preparative electrophoresis or FPLC were similar. Tests using the purified omega-gliadin fraction present the best performance when anti-gliadin antibodies are evaluated.
