Fig 1. Degradation of gliadin as monitored by R5 ELISA immunoassay.

Fig 1

Degradation of gliadin was monitored as a function of time at pH 4.5 (A) and pH 6.2 (B), using AN-PEP as a control enzyme. To exclude the presence of an interfering substance in digestive enzyme supplements we also analyzed AN-PEP control enzyme in the presence of Supplement C. Error bars represent standard deviation of duplicate experiments. Supplements D and E were not tested since they were not compatible with R5 ELISA immunoassay procedure.
