METHODS AND MEANS FOR EXPRESSION OF MAMMALIAN POLYPEPTIDES IN MONOCOTYLEDONOUS PLANTS

摘要

Rice, wheat and other monocotyledonous plants are transformed with expression cassettes for production of mammalian polypeptides, such as antibodies. Endoplasmic reticulum (ER) retention signals, 5'untranslated regions and leader peptides are employed in various combinations to provide high expression yield. Multi-chain complexes such as four-chain secretory antibodies are produced by expression of component polypeptides from separate vectors all introduced into the same cell by transformation.
