Immunological study of different fraction of wheat proteins

Wheat allergy specifically refers to the adverse reaction involving IgE antibody to one or more protein fraction of wheat such as albumin, globulin, gliadin and glutenin [gluten]. The majority of IgE-mediated reactions to wheat involve albumin and globulin fraction while gluten [gliadin and glutenin] also cause allergy [Celiac disease]. Allergic reactions to wheat may be caused by ingestion of wheat containing foods or inhalation of flour [Bakers asthma]. The present study was an effort to explore the antibody response of different proteins present in wheat. ELISA results revealed that the antibody response for albumin varied from 0.92-1.78, whereas, for globulin ranged from 1.39-1.60. Antibody response against glutenin and gliadin ranged from 0.57-1.05 and 0.98-1.95 respectively, among the different varieties of wheat. All the tested wheat varieties showed the significant difference antibody response against the different fractions of protein
