Description

一种HCV病毒NS5A蛋白编码序列突变检测试剂盒
技术领域
本发明涉及分子生物学检测领域,具体涉及一种HCV病毒NS5A蛋白编码序列突变检测试剂盒
背景技术
HCV基因组可分为3个区域,即5’非编码区(5’UTR)、编码区(ORF)、3’非编码区(3’UTR)。5’UTR为高度保守区,是病毒翻译的起始位点,在HCV复制过程中有非常重要的作用。开放读码框架(ORF)包括结构蛋白区C、E1、E2和非结构蛋白区P7、NS2-NS5。包膜区(E1、E2)和核心区(C)编码病毒颗粒,非结构蛋白区在病毒复制和病毒蛋白合成中起重要作用。3’UTR为加尾结构。其中NS3/4A、NS5A和NS5B是直接抗病毒药物(DAAs)的作用靶点。在对HCV1b型基因序列的研究中,许多报道发现HCV NS5A蛋白多个区域的氨基酸(amino acid,aa)序列突变与IFN、IFN/RBV的疗效有关,但是NS5A蛋白在HCV病毒不同基因型中存在序列差异,且容易突变。
发明内容
本发明要解决的技术问题是针对HCV病毒NS5A蛋白易突变的问题,提供一种HCV病毒NS5A蛋白编码序列突变检测试剂盒。
本发明采用的技术方案是:提供一种HCV病毒NS5A蛋白编码序列突变检测试剂盒,包含一组RT-PCR引物组1和一组设置于编码NS5A蛋白序列两端的,按照HCV基因序列互补编码的扩增引物组2,还包含一组设置于编码NS5A蛋白序列两端的,按照HCV基因序列编码的扩增引物组3,所述扩增引物组3的编码序列包含在按照引物组2扩增的基因片段内。利用多组引物组扩增出符合测序要求的高质量基因片段。
本发明具备的有益效果为:极大的提高了检测的敏感性和特异性,降低了对HCV病毒样品制备的要求,检测灵敏度高,结果可靠。

图2 RT-PCR扩增产物琼脂糖凝胶电泳图2
图3 RT-PCR扩增产物琼脂糖凝胶电泳图3
图4二次PCR扩增产物琼脂糖凝胶电泳
具体实施方式
设计方案为:选取203例HCV1b型病毒样本,处理得到病毒的RNA核酸样品,利用引物组1一步法RT-PCR法扩增出NS5A区片段,琼脂糖凝胶电泳鉴定扩增片段的正确性及产物大致浓度,满足ABI3730测序仪测序要求时利用ABI3730测序仪进行测序;未满足测序要求的样本以第一轮扩增产物为模板利用引物组2进行进一步的PCR扩增,对不满足测序要求的样品进一步利用引物组3进行扩增。对满足测序要求的扩增产物测序完成后,使用序列分析软件Sequencher将测序图谱与HCV参考株序列进行比对,进而确定分析位点的氨基酸变异情况。本实施例所选用的设备仪器包括:Biorad S1000PCR仪、Biorad PAC300电泳仪、Biorad凝胶成像系统、ABI3730测序仪。本实施例使用的引物序列为:
PCR试剂为选取Vazyme产品(HiScript II One Step RT-PCR Kit),包括:

第二或三轮PCR扩增条件为:
第1轮RT-PCR结果如图1-3所示,第二轮PCR结果如图4所示。对凝聚电
泳的分析如下:
上述203例检测结果进行统计分析显示,第一轮RT-PCR检测成功率为92.10%(187/203),对未达到测序要求的样本进行第二轮巢式PCR后成功率为81.25%(13/16);两轮PCR扩增后总体成功率为98.52%(200/203)。本次验证过程中共有三例样本(T1012、T1015、T386)检测失败,对这三例样本重新进行了测序法分型检测,检测结果显示T1012为6n亚型,T1015、T386为6型,因此本次验证实验失败样本的原因为HCV基因型别判定错误造成。除去三例型别不符样本外,第一轮RT-PCR检测成功率为93.5%(187/200),对未达到测序要求的样本进行第二轮PCR后成功率为100%(13/13);两轮PCR扩增后总体成功率为100%。
随机选择了47例第一轮扩增成功的样本以及全部13例第二轮扩增成功样本,共计60例样本进行测序。
备注:1.突变型Cutoff:20%;2.*代表首次测序正反向序列93位点结果不一致。
从上述结果中可以看出,60例样本中31位氨基酸突变仅发生两例(3.33%),93位氨基酸有5例样本发生突变(8.33%);但还有7例样本出现93位点正反向测序结果不一致的情况,主要表现为正向测序为野生型,而反向测序时则出现了突变型与野生型共存。
