So now, for example, there are a whole range, just a whole rainbow of fluorescent proteins that can be used.

现在，人们可以用的荧光范围，达到整个彩虹色谱。

You could watch where it localizes in the cell, there are fluorescent assays you could use to determine what other proteins it interacts with.

你可以看到它在细胞的什么地方，你可以用荧光化验的办法确定,它和其它什么蛋白质相作用。

He actually recognized and, of course, many people recognized that this jellyfish was fluorescent, and he isolated the actual protein, and determined and proved that this protein was sufficient to cause this fluorescence.

他认识到了，当然，很多人都认识到了水母是有萤光的，它分离出了这种蛋白质，测定了它并证明,这种蛋白质会导致萤光。

For some of you that haven't I'll just say that it's a protein, it's 238 amino acids, which means that it's about 1,000, actually more than 1,000 atoms in size, and this protein is fluorescent.

对于那些没听说过的人,我要说它是一种蛋白质，它有238个氨基酸，也就意味着它有约1000个，实际上是超过1000个原子，这种蛋白质是有萤光的。

And once he did that, both he and many other scientists, could then, once they understood what caused the fluorescence, make little changes to the actual protein, and tune what the properties of that fluorescent protein were.

而且一旦他做成了这个，一旦他们弄清楚了是什么导致萤光，他和其它很多科学家，就可以对蛋白质做微小的改变，调节蛋白质的荧光性质。
