The Phage-ligand technology is a technology to detect, bind, and remove bacteria and bacterial toxins by using highly specific bacteriophage-derived proteins.Technological background
Origins The host recognition of bacteriophages occurs via bacteria-binding proteins that have strong binding affinities to specific protein or carbohydrate structures on the surface of the bacterial host. At the end of the infection life cycle, the bacteria-lysing Endolysin is synthesized and degrades the bacterial peptidoglycan cell wall, resulting in lysis (and therefore killing) of the bacterial cell.
