摘要: 目的 建立法医物证学常染色体和Y染色体综合检测的方法。 方法 选择常用的常染色体STR基因座和Y染色体STR基因座,设计复合扩增引物,形成五色荧光标记复合扩增试剂盒。 结果 开发出一个五色荧光标记复合扩增试剂盒,可同时对15个常染色体STR基因座、1个性别基因座和10个Y染色体STR基因座进行分型检测。 结论 15个常染色体STR加10个Y染色体STR检测试剂盒结合毛细管电泳凝胶进行STR分型,结果准确可靠,在法医学案件检验及数据库建设等方面有良好的应用前景。

Abstract: Objective To establish a multiplex STR genotyping method for autosomal STR and Y-STR loci in forensic biological practice. Methods Widely used autosomal STR loci and Y-STR loci were selected. A set of PCR primers was designed, and a 5-dye fluorescent labeled STR multiplex PCR reagent kit was developed. Results A kit was developed which can simultaneously detect 15 autosomal STR loci, 10 Y-STR loci, and an Amelogenin. Conclusion The 15 autosomal STR plus 10 Y-STR kit in combination with capillary electrophoresis method was used to STR genotyping with accurate and reliable results. The new one-step testing kit can potentially be widely used in forensic cases and DNA databank in the future.
