Figure 1.

Fecal glutenase activity (FGA) of non-celiac disease (NCD) volunteers. (A) Bioassay results showed the gluten was degraded in solid gluten media. Data represented as the mean ± SEM, in terms of the number of units of trypsin/g feces. Representative SDS-PAGE (B) and gliadin zymogram (C) results from whole-protein fecal samples from non-CD volunteers (1–8). M: electrophoretic molecular weight marker. The boxed-in areas correspond to the 3 zones with gliadinase activity, as determined by densitometric analysis at >97, 45–35, and 30–25 kDa.
