  3. miRNA形成过程

  4. 前体

  5. 成熟体

  6. 加尾法定量PCR(QIAGEN) 茎环法定量PCR(RIBO) SYBR荧光定量检测miRNA

  7. 加尾法原理

  8. 茎环法原理

  9. 两种方法的比较

  10. rno-miR-34b 茎环法 加尾法

  11. hsa-miR-99a 茎环法 加尾法

  12. hsa-miR-99a表达量比较

  13. 1.根据我们的经验,大部分样品中pre-miRNA含量很低甚至没有,可以采用QIAGEN加尾法进行miRNA的定量PCR检测。1.根据我们的经验,大部分样品中pre-miRNA含量很低甚至没有,可以采用QIAGEN加尾法进行miRNA的定量PCR检测。 2.PCR特异性都很好的时候,两种方法得到的相对表达量一致。 3.对于加尾法预实验有非特异性扩增的样品,采用RIBO茎环法进行检测。 策略
