同位素标记的 meaning in Chinese

isotope-labelled

The experiment in which 13c - trioctanoin was used as a labeled substrate to diagnose the disease about fat malabsorption was explained and followed by a research on the diagnosis of the same disease with 13c - substrate
摘要介绍了用13c -三辛酸甘油酯为标记药物通过呼气实验诊断脂肪代谢疾病的方法，进而引出了用稳定同位素标记的类似药物来诊断同样疾病的研究。
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。
