But experts say it will be very difficult to isolate this part of the protein from the virus to use in a vaccine, or to manufacture it using genetic engineering.

不过，专家们说，很难从病毒中分离出这部分蛋白质用于疫苗，或利用基因工程生产出这种蛋白质。

At first Amgen tried using genetic engineering to create organisms that would extract oil from shale, man-made proteins that would make chickens grow faster and new specialty chemicals such as a cloned indigo, a substitute for the natural dye used to color blue jeans.

FORBES: Biotech Behemoth

Dr. LEE RYBECK LYND (Professor of Engineering, Adjunct Professor of Biology, Dartmouth College): In my lab, one of the big ideas we're working on, is to try to develop microorganisms using genetic engineering, that let us do, in one step, what we're now only able to do in more than one step.
