Protein microspheres and methods of using them

摘要: Biodegradable, protein microspheres for in vivo release of a biologically active agent, as well agricultural and environmental applications. The can be administered orally, intravenously, or subcutaneously subsequent release. By selecting particular size ranges the specific used to form microsphere, it is possible target cell types such macrophages, effect localized absorption regions mucosal membranes mouth, gastrointestinal tract, urogenital areas. Larger forms also made using standard techniques desirable degradation properties.
