如他们展示的放大图像那样，火箭捕获了一个表达有癌胚抗原的癌细胞。

As they zoom along, the rockets capture cancer cells that express corresponding antigenic surface proteins.

虽然尼人遗传给欧洲人的DNA仅有6%，但是人类目前所发现的白细胞抗原等位基因中，有一半来源于尼人的贡献。

Though the contribution to European DNA from Neanderthals is only about 6 percent, that small percentage accounts for half the observed human leukocyte antigen alleles.

它可为细胞提供身分，例如红血球表面的抗原使血液有血型。

It provides identity to the cell. eg. antigens on red blood cell in relation to blood group.

So, now you have a single molecule, very large molecule, with not just two binding sites but with ten binding sites.

所以如果你体内有一个细胞,一个体积很大的细胞,细胞表面不只有两个抗原结合位点,而有十个抗原结合位点

The advantage of this is that now you have four binding sites for antigen instead of just two.

这样的好处是一个抗体上,有四个抗原结合位点而不仅仅是两个

So, these are better at binding to antigen because they have more binding sites on them.

连接抗体是对付抗原的有效方法,因为抗体表面将会有更多的抗原结合位点
