Characterization of the specificity of aptamer CCFM641-5 for B. bifidum. Selected aptamer sequence CCFM641-5 preferentially bound to B. bifidum over other species of bacteria. (A) Flow cytometric analysis of aptamer CCFM641-5 binding for different species of bacteria which are shown with differently colored curves; (B) Histogram of the percent gated fluorescence intensity above background for aptamer CCFM641-5. The values of aptamer binding represent the mean ± SD of three independent experiments. Bars with different letters are significantly different (p < 0.05).
