定量PCR(qPCR,又称Real-time PCR)是一种非常通用的精确分析基因表达的技术。按方法不同可分为染料法和探针法两类,其中染料法更通用、方便、成本更低。基于染料的qPCR法通过实时监测结合双链DNA的染料发射的荧光,可以在PCR的每个周期间接测量DNA扩增。当在某一个时间点上,检测到的荧光信号显著超过背景,就可以确定Ct值(Cq值)。所获得的Ct值可用于评估目标基因的相对丰度,也可根据适当的标准曲线计算获得绝对数量。
我们的产品HotStart™ Universal 2X SYBR Green qPCR Master Mix在定量目标DNA或cDNA方面具有优越的特异性、强劲的扩增效率、理想的可重复性和稳定性。它是一个2X PreMix,使用了新型结合抗体的热启动Taq DNA聚合酶。理想的Taq聚合酶和合适的缓冲液保证了较好的特异性和较高的扩增速度。Mix中的SYBR Green I可嵌入双链DNA的双螺旋小沟区域,当它与每个周期扩增的双链DNA结合时,会发出绿色荧光,通过仪器监测荧光可以实时的间接定量扩增产物。
该试剂含有特殊的Specific ROX Reference Dye,适用于所有的qPCR仪器,无需在不同的仪器上调整ROX的浓度,只需在配制反应体系时加入引物和模板即可进行扩增。染料法qPCR有一定的局限性,即SYBR Green I可以插入任何双链DNA,如引物二聚体或其他非特异性的产物,导致非特异性产物发出荧光,因此为了确认产物的特异性,在扩增后,进行溶解曲线分析是必要的。在溶解曲线分析中,在引物退火温度附近出现一个尖峰是较为理想的实验结果。
