single domain binding unit capable of binding to a virus is described. Preferably the protein is a

Food pharmaceutical and cosmetic products comprising such proteins are also described together
with a method for selecting inhibiting proteins from a large population of mainly containing noninhibiting,
but infectious agent binding fragments.
