产品详情

BRAF RGQ PCR Kit仅用于科研,可通过在Rotor-Gene Q 5plex HRM Instrument上的real-time PCR检测BRAF基因的V600E突变。此试剂盒包含所有必需的试剂,优化后可在野生型基因组DNA背景下快速、灵敏的检测低含量的突变DNA。ARMS PCR技术配合Scorpions检测技术,可对特定突变进行高灵敏度和特异性的检测。

原理

BRAF RGQ PCR Kit是一种即用型试剂盒,可在Rotor-Gene Q实时荧光定量PCR分析仪上利用聚合酶链反应(PCR)检测BRAF基因的V600E体细胞突变。BRAF基因编码V-raf小鼠肉瘤病毒癌基因同源物激酶B1,是EGFR下游的原癌基因。此试剂盒可定性检测BRAF原癌基因的V600E体细胞突变,模板是从福尔马林固定、石蜡包埋(FFPE)样本中提取的基因组DNA。

BRAF RGQ PCR Kit可在野生型基因组DNA背景下检测以下突变。

  • V600E common (GAG)
  • V600E complex (GAA)和V600D (GAT)
  • V600K (AAG)

此试剂盒可检测V600E复合物(GAA)和V600D(GAT),但并不能区分二者。检测V600K(AAG)突变高度依赖于V600K的拷贝数。

BRAF 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

BRAF RGQ PCR Kit为两步操作流程。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

BRAF RGQ PCR Kit可在野生型基因组DNA背景下检测以下突变。

  • V600E common (GAG)
  • V600E complex (GAA)和V600D (GAT)
  • V600K (AAG)
