Flow cytometry analysis of inhibition of Plg binding to B. lactis BI07 and B. longum S123 by EACA and after pretreatment with carboxypeptidase B. (A) Bifidobacteria were incubated with 1, 10, and 50 μg EACA and 2.5 μg of Plg. Bacterial surface-bound Plg was detected with FITC-labeled antibody. The results indicate that there was dose-dependent inhibition of Plg binding by EACA. (B) Plg binding to bifidobacteria after treatment of the bacteria with 5 and 25 U carboxypeptidase B. The shift in fluorescence intensity is shown in plots of representative results.
