产品详情

KRAS RGQ PCR Kit是仅限于科研应用的检测,可通过在Rotor-Gene Q 5plex HRM仪器上的real-time PCR检测KRAS基因的7个体细胞突变。KRAS RGQ PCR Kit利用ARMS和Scorpions技术,可在野生型基因组DNA背景下检测KRAS原癌基因的12和13位密码子的突变。

原理

KRAS RGQ PCR Kit是一种即用型试剂盒,可在Rotor-Gene Q 5plex HRM仪器上利用real-time PCR检测KRAS基因的7个体细胞突变。KRAS基因编码的蛋白在EGFR信号通路中发挥重要作用。KRAS基因的突变会影响蛋白刺激下游通路。KRAS基因在各种癌症类型中约30%会发生突变。高频率KRAS突变的癌症包括结直肠癌(35%)和肺癌(18%)。

KRAS RGQ PCR Kit利用两种技术,即ARMS(Amplification Refractory Mutation System)和Scorpions,通过real-time PCR检测突变。

ARMS

通过ARMS可进行等位基因或突变特异性扩增。Taq DNA聚合酶可有效区分PCR引物3'端的搭配与错配。特定突变序列被选择性扩增,即使样本中大部分序列都不含有此突变。当引物完全搭配时,扩增过程非常高效。当3'端碱基错配时,只有低水平背景扩增发生。

Scorpions

使用Scorpions检测扩增。Scorpions是双功能分子,含有一个共价连接到探针上的PCR引物。探针上的荧光基团与同样在探针上的淬灭基团相互作用,降低了荧光强度。PCR过程中,当探针结合到扩增子上时,荧光基团和淬灭基团就会分开,导致反应管中荧光强度增加。

程序

KRAS RGQ PCR Kit包括一个两步操作流程。第一步是对照分析,以检测样本中的总DNA。第二步是突变分析,以检测是否存在突变的DNA。

应用

KRAS RGQ PCR Kit可检测KRAS基因的7个体细胞突变,并对突变状态进行定性分析。
