您要查找的是不是：
- Colorless materials can be used if some means of detecting them is used (electronic detection, radioactive labeling, or ninhydrin developer). 如果运用一些其他的检测方法（电子检测，放射性标记，茚三酮等）无色的物质也可以使用。
- Furthermore, radioactive labeling followed by subcellular fractionation showed that a significant portion of the newly synthesized GRP78 is localized to the mitochondria in cells under UPR. 利用放射线标示新合成蛋白质并接著进行胞器分离实验，结果显示当细胞遭遇内质网逆境，新合成的GRP78会目标导向进入粒线体。
- The former entails the cumbersome sampling, electrophoretic separation, and quantitation of the reaction products, as well as the continuous loss of substrate due to decay of the radioactive label. 但在实际操作中，这两种方法都存在一定的困难。
- radioactive labeling(radiolabeling) 放射性标记术
- By incubating these isotopes with bacteriophages during the replication cycle, they obtained versions tagged with both radioactive labels. 通过同位素与复制阶段的噬菌体共同培养，他们获得了同时被两种放射性元素标记的标本。
- The permeation of MPS into superficial tissue was demonstrated using a radioactive labeled substance as well as chemical-analytical and histochemical methods. 用放射活性标记物质、化学分析和组织化学法证实MPS(多磺酸粘多糖）能渗透入浅表组织。
- The metabolic pathways of organic compounds have often been delineated by using a radioactively labeled substrate and following the fate of the label. 有机化合物的代谢途径经常用放射性标记的底物并对其进行跟踪来描述。
- Radioactive ray is material thing. 放射线是实际的物质。
- radioactive labeled tracer compounds 放射性标记示踪化合物
- He attached a label to his baggage. 他往行李上贴了一个标签。
- Radium and uranium are radioactive elements. 镭和铀是放射性元素。
- His work is difficult to label accurately. 他的工作很难准确归类。
- Attach the label to your luggage. 把标签贴(系)在你的行李上。
- A certain discharge of possible radioactive effluent. 一定量的可能有放射性的废水。
- He'll attach the label to your luggage. 他会把标签系在你的行李上。
- There is a label on the inside of the box. 盒子内侧有个标签。
- Someone has sticked a label on the crate. 有人在板条箱上贴了标签。
- Another proprietary antibody that binds to CD20, called tositumomab, is radioactively labelled. 他们使用另外一种放射标记的连接CD20的抗体：tositumomab。
- An indelible pen for labeling clothing. 一种为衣物作标签用的其笔迹很难去掉的笔
- A radioactive isotope of carbon, especially carbon 14. 放射性碳碳的一种放射性同位素，尤指碳14。
