摘要:The aim of this study was to investigate the influence of non-enzymatic glycosylation on the immunogenic properties of soluble wheat proteins. Albumin/globulin fractions of herbicide resistant wheat line were non-enzymatically glycosylated using glucose for seven days at 37°C. The changes in their structures and immunoreactivity were then determined. The protein fractions were also hydrolysed with pepsin to determine the resistance to digestion. Albumin/globulin fractions before and after non-enzymatic glycosylation were analysed using o -phthaldialdehyde method and sodium dodecyl sulphate-polyacrylamide gel electrophoresis. The immunoreactivity of the protein fractions was determined using enzyme-linked immunosorbent assay methods, as well as affinity chromatography. The soluble wheat proteins showed smaller amounts of available α-amino groups after non-enzymatic glycosylation, and were stronger immunogens after glycation, but their antigenicity was not been affected significantly. However, pepsin hydrolysis of wheat proteins decreased their immunoreactivity.
