Fig. 3. Effects of preincubation of H. pylori suspension with 0, 100, 400, and 1600 µg/ml MUC5B. These results show that preincubation of H. pylori reduces adherence in a dose-dependent manner, indicating that the observed adherence is MUC5B dependent. Adherence was quantified as an index value based on a pooled saliva sample as a standard.
