摘要
目的:探讨单核苷酸多态性(single nucleotide polymmphism,SNP)分型前聚丙烯酰胺凝胶电泳(polyaerylamide gel electro—phoresis,PAGE)的作用。方法:对3个DNA片段(DAOA基因的片段E1和E2、RGS4基因的片段S4)的PCR产物先用PAGE分析,然后用变性高效液相色谱(denaturing high performance liquid chromatography,DHPLC)分型,并比对结果。结果:PAGE能将片段E1、E2和S4中同一位点的SNP杂合子样本和纯合子样本区分开来,还能进一步将片段S4中SNP位点的2种不同纯合子样本区分开来。结论:PAGE能提高SNP的检测效率,而且具有成本低,操作简便的特点。
