Applications

  • Lactose has been used in vitro to interact with carbohydrate recognition domains on a recombinant form of LGALS9, thus blocking downstream functions of the protein
  • It has been used as a control to study sugar dependency in Drosophila, which do not digest lactose
  • As a common component of pharmaceutical tablets, alpha-lactose has been used in laboratory settings to imitate drug administration
