费用比

• It has been estimated that the cost of producing proteins in transgenic plants may be 100 fold lower than in transgenic animals or mammalian cell cultures , and the possibility of using the plant tissue as a carrier for oral deliery could also diminish the expensie step of recombinant protein purification
  估计在转基因植物中生产蛋白的费用比用转基因动物或者哺乳动物细胞培养的方法要便宜100倍，而且用植物组织可以作为口服递送载体，这点同样减少了高花费的重组蛋白纯化步骤。
