摘要： A new, reliable, easily scalable and reproducible method for the production of recombinant butyrylcholinesterase (rBuChE) is provided. Through the utilization of a plant transfection procedure, various plant strains have been shown to generate effective and scalable amounts of rBuChE under acceptable manufacturing processes to permit reliable levels of such enzymes for desired nerve agent protection requirements (including tetrameric products). As well, such methods in engineered plant lines have shown suitable production of these enzymes in tetramer form with glycan formation and sialylation (for terminal groups) to allow for optimal potency against organophosphorus agent exposure as well as proper immunogenic response within the plant sources. The overall production method, including the transfection and production within mammalian cells, as well as the process steps involved for such a reliable sourcing platform from plants is thus encompassed within the invention.
