  • Patent number: 5013552
    Abstract: Loaded pollen grains are disclosed which are suitable for use as delivery systems for introducing biologically active substances into or on plants and animals. Such pollen grains are suitable to deliver both small and large (macromolecules) molecules. Preferred pollen grains are those that have been defatted and then pre-treated to be free of antigenic materials and that have special surface features that facilitate their attachment to tissue surfaces, particularly to mucous membranes. The most preferred pollen grains are those that have spiny or irregular or fragmented surfaces. Also disclosed are a method of pre-treating the pollen grains to remove antigenic materials; a method of loading the pollen grains with the biologically active material; and a method of incorporating such pre-treated, loaded pollen grains into formulations or dosage forms suitable for introduction into or on a plant or animal body.
