产品详情

KRAS Pyro Kit是用于鉴定KRAS基因中突变的分子检测试剂盒。该试剂盒包含扩增KRAS基因所需的引物和试剂、外加缓冲液、引物和试剂，在PyroMark Q24 System上使用焦磷酸测序技术实时定量检测突变。

原理

KRAS Pyro Kit用于实时定量检测人KRAS基因编码子12、13和61的突变，在PyroMark Q24 System上使用焦磷酸测序技术检测。KRAS基因编码一种在EGFR信号通路中有重要作用的蛋白。KRAS基因的突变会影响该蛋白对下游通路的激活。所有癌症中将近30%发生KRAS基因突变，其中直肠癌（35%）和肺癌（18%）。

可检测以下种类的突变：

编码子12/13：G12A、G12C、G12D、G12R、G12S、G12V和G13D
编码子61：Q61E、Q61H、Q61L和Q61R

程序

该试剂盒包含2部分实验：一个用于检测编码子12和13的突变；另一个用于检测编码子61的突变（参见""和""）。运用PCR技术对这两个片段分别进行扩增，测定特定区域的核酸序列。使用该法进行定量和定性分析时，特定区域周围的核酸序列峰被视为标准峰和参照峰。

使用针对编码子12/13和编码子61的引物对两个片段PCR扩增后，将扩增子固定在高性能链霉素亲和琼脂糖上。将单链DNA和相应序列的引物退火处理得到DNA。然后在PyroMark Q24 System上设置程序和运行程序对样品进行分析。推荐使用KRAS Plug-in Report进行分析。该报告确保使用正确的LODs和分析的不同序列可自动检测所有突变。也可在PyroMark Q24 System上使用其他分析工具进行分析（参见" Pyrogram trace of a GGT to GAT mutation in base 2 of codon 12"）。运行后可以通过调节"Sequence to Analyze"来检测稀有突变（参见" Pyrogram trace of a GGT to TGT mutation in base 1 of codon 12"和" Pyrogram trace of the reanalysis of the sample in the previous figure"）。

FAQ

The NRAS Pyro, EGFR Pyro. BRAF Pyro, KRAS Pyro, and UGT1A1 Pyro Kits all require that no more than 10ng of DNA be used for the PCR reaction. Too much DNA can sometimes lead to inhibition problems in the PCR reaction.

FAQ ID -2379

Mutation assays designed by QIAGEN detect the most common mutations. In addition, QIAGEN provides plug-ins to analyze more mutations and convenient reports for PyroMark KRAS, PyroMark EGFR, and PyroMark BRAF kits. The plug-ins can be obtained by emailing pyro.plugin@qiagen.com

If the mutation cannot be analyzed successfully, please send the original run files to QIAGEN Technical Service for further assistance.

FAQ ID -9065

Mutations in KRAS codon 61 must be analyzed separately with the KRAS Plug-in and not with the RAS extension plug-in.
