浅述ALK融合突变及其检测方法(上) - 知乎
ALK基因全称为间变性淋巴瘤激酶(anaplastic lymphoma kinase,ALK),总共有29个外显子。 为了方便理解,各位可以将它想象成一辆名为ALK的高铁列车,而29个外显子就是列车的29节车厢,那么“融合突变”就是 指ALK的某节车厢断裂并且与其他班次的列车车厢相接变成一个新的列车,最常见的是从ALK号列车的20号车厢处断裂,并与另一辆名为“ EML4 ”的基因重新拼接,如下所示。 已发现的所有ALK基因融合突变都是在ALK基因外显子20处发生断裂,而EML4断裂点有 …
浅谈ALK 融合基因检测中IHC与FISH方法孰优孰劣?
2015年12月25日 · 目前分子病理的检测工作中,ALK基因的融合主要有三种方法,荧光定量PCR法(RT-PCR),免疫组化法(IHC)和荧光原位杂交法(FISH)。 以上方法中,因为荧光定量PCR法对实验室的防污染要求比较严格,需要专门的PCR实验室来完成,核酸提取及PCR扩增等环节。 因此,荧光定量法在实际应用中的推广与免疫组化法和原位杂交法相比,普及率较低。 因此本文着重讨论在ALK的融合基因检测中,IHC与FISH两种方法的比较。 在 2014 年,法国的雷 …
