Visualization of Bovine Lactoferrin Binding to Bifidobacteria

Abstract

In the present study, binding of bovine lactoferrin to bifidobacteria was demonstrated. This is the first report showing the binding of bovine lactoferrin to Bifidobactesrium spp. under a transmission electronic microscope using biotinylated bovine lactoferrin and gold-conjugated streptavidin. In addition, we confirmed that bovine lactoferrin-binding protein exists on the surface of bifidobacteria.
