  • Lactalbumin production process
    Patent number: 7524932
    Abstract: A method for producing an oligomeric form of ?-lactalbumin which is in the molten globule-like state is described. The method suitably comprises exposing a source of ?-lactalbumin in which the ?-lactalbumin is preferably in the molten globule-like state, to an ion exchange medium which has been pre-treated with casein or an active component thereof, such as oleic acid, and recovering ?-lactalbumin in an oligomeric form therefrom. Pre-treatment of the ion exchange medium, particularly with casein derived from human milk, has been found to significantly improve yields of the oligomeric form of ?-lactalbumin and mean that it can readily isolated from readily available sources such as bovine ?-lactalbumin. This form of ?-lactalbumin is useful therapeutically, in particular as an antibacterial agent and also as an anti-cancer therapeutic.

  • Therapeutic agents
    Patent number: 6808930
    Abstract: An agent comprising a protein complex comprising an oligomeric form of &agr;-lactalbumin (MAL) and a further reagent which is combined with MAL such that it is carried into the nucleoplasm of cells which are susceptible to MAL. Agents of the type, where the further reagent is a therapeutic or labelling reagent, can be used in diagnosis and therapy in particular of cancer.
