Method for preparing virus like particles (TSPs) derived from Plants

摘要

Methods for preparing virus like particles (TSPs) derived from plants. The Method may include obtaining a plant or Plant material including PSV, located in the apoplastos, produce a fraction of a fraction of esferoplastos protoplasts and / apoplastos from plant material or Plant and recover the apoplastos fraction.The fraction of the apoplastos comprises the PSV derived from plants. Alternatively, the PSV can be obtained from a plant or a Plant material including PSV from Plants by the digestion of Plant material with a composition comprising an enzyme capable of degrading the cell wall, thus producing a fraction digested.The fraction digested filtered to produce a filtered fraction derived from plants, and the PSV are recovered from the filtered fraction. Claim 32: the method of claim 29, wherein the PSV derived from Plants include influenza hemagglutinin.
