摘要 本研究以β微管蛋白基因作为内参基因,采用实时荧光定量PCR方法检测该基因在扩展莫尼茨绦虫(Moniezia expansa)4个不同发育阶段,即头节、幼节、成节和孕节中的表达差异。标准曲线分析显示,翻译延伸因子、引发酶基因和β微管蛋白基因标准质粒实时定量扩增Ct值与标准质粒的浓度均呈良好的线性关系,相关系数(R2)均大于0.99。同时实验结果显示,翻译延伸因子和引发酶基因在虫体各发育阶段中的转录水平存在差异。其中,翻译延伸因子和引发酶基因在扩展莫尼茨绦虫头节和幼节的转录水平均较高,提示这2个基因可能在头节和幼节的发育中有重要作用。 A SYBR green real-time fluorescent quantitative PCR assay was developed for detection of Moniezia expansa mRNA with its beta-tubulin as an internal control. The results showed a good linear relationship （〉0.99）between the Ct value and the concentration of positive plasmid for each gene from scolex and various proglottids. Real-time PCR showed that the expression abundance of translation elongation factor and primase was different. In conclusion, the tran- scription level of translation elongation factor and primase was high in both scolex and immature segment, suggesting that they may olav a role in the develonment of scolex and immature segment.
