radioactive labelling meaning in English
示踪标记
Examples
- 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。 - 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。 - Although this method gives high sensitivity , the radioactive labels present many problems such as a potential hazard to analyst and environment , which limited its application in dna diagnostic laboratories . in order to overcome these problems a serious of non - radioactive dna probes such as fluorescent , chemiluminescent and electrochemical probes have been developed . although these new methods display many advantages , they have not been used to take place completely the traditional method because of low sensitivity or complex equipment or other shortcomings
自20世纪80年代以来，各种非同位素如酶、荧光素、生物素、地高辛标记的化学发光法和荧光分析法以及以电活性物质做标记的电化学方法相继问世，这些方法虽然在一定程度上克服了同位素标记的缺陷，但由于存在灵敏度不够高或检测系统庞杂或仪器价格昂贵或标记物不稳定等缺陷，还不能完全取代传统方法。
