Association of Levels of Antibodies from Patients with Inflammatory Bowel Disease with Extracellular Proteins of Food and Probiotic Bacteria

Figure 1

(a) Immunoreactive bands corresponding to antibodies present in the sera of healthy controls or IBD patients raised against the extracellular proteins of the bacterial strains used in this study. (b) Western blotting analysis showing different patterns of sera immunoreactivity against extracellular proteins produced by the strains used in this study (C# healthy controls; P# IBD patients). In all cases, a secondary anti-human IgA antibody, HRP conjugated, was used. The order of the lanes (lines 1 to 6) correspond to that of the SDS-PAGE.
