Tagging the human cells with fluorescent markers allowed the researchers to track where in the developing embryo they, and their descendants, went.

用荧光标记物标记人类细胞，研究人员就能够追踪这些细胞及其后代在发育的胚胎中的位置。

We can even mark certain specimens with fluorescent markers and then let them go, so we can observe them night after night.

我们甚至可以对特定目标做上荧光标记，然后把它们放走，这样就能每晚对它们进行观察。

To solve that mystery, the researchers exposed 79 slugs to more than a million nematodes that had been tagged with a fluorescent marker.

为了揭开这个谜团，研究人员们将79只鼻涕虫放在用荧光标记过的100万多只线虫环境中。

First, proteins of interest are tagged with fluorescent markers.

首先，感兴趣的蛋白质用荧光标记物标记。

The gel expands, bringing the fluorescent markers along with it.

凝胶膨胀，荧光标记随之膨胀。

To this problem Dr Boyden has devised a new solution: adding the fluorescent markers after expansion of the sample, rather than before.

针对这个问题，Boyden 博士设计了一个新的解决方案：在样本扩展之后添加荧光标记，而不是之前。

She was then able to attach fluorescent marker molecules to those glycans once they were exposed to the outside world, by fitting the markers with strained-alkyne rings.

然后，一旦这些聚糖暴露在外界环境中，她就可以将荧光标记分子附加到这些聚糖上，方法是将标记物与应变炔环相匹配。

This DNA contains a modified version of a gene called OX513 that makes the mosquitoes express two traits: One is a red fluorescent marker protein, so scientists can tell in a lab which mosquito larvae have the modified gene.

该 DNA 包含一种名为 OX513 的基因的修饰版本，该基因使蚊子表达两种特征：一种是红色荧光标记蛋白，因此科学家可以在实验室中分辨出哪些蚊子幼虫具有修饰基因。
