And so what we did is, we take tissue culture cells and infect them with various viruses, and we take the stuff and fluorescently label the nucleic acid, the genetic material that comes out of these tissue culture cells -- mostly viral stuff -- and stick it on the array to see where it sticks.
我们所做的就是提取组织培养细胞， 用不同的病毒感染它们， 用荧光标记核酸， 来自这些组织培养细胞的遗传物质—— 大部分是病毒类的东西——把它粘在芯片上。
