Background and objective : It is generally accepted that one third of children with food allergy lose their clinical activity if the responsible food allergen can be identified and completely eliminated from their diet. But buckwheat allergy rarely lose clinical activity. So, we have produced hypoallergenic buckwheat(HBW) according to Ikezawa's method, and characterized the allergenicity by immunoblot method using monoclonal antibodies to raw buckwheat. Material and Methods : HBW was prepared from raw buckwheat by salting with 0.5 M NaCl. 18 monoclonal antibodies to raw buckwheat were made according to standard polyethylene glycol method. We performed SDS-PAGE of HBW and transferred to nitrocellulose membranes, which were immunoblotted by selected 3 monoclonal antibodies to raw buckwheat. Results : The protein concentration of HBW was 47.3 μg/μL. As the result of SDS-PAGE of HBW the protein bands of 50, 36, 13 kD of raw buckwheat disappeared. 3 monoclonal antibodies were selected due to their higher specificities in ELISA. Immunoblot study showed that 2 among 3 monoclonal antibodies bind to HBW. Conclusion : The SDS-PAGE of HBW showed less protein bands in comparison to raw buckwheat. But the allergic component of HBW still remained. So further studies are required to eliminate the residual allergenicity of hypoallergenic food.
