[Abstract] Recent advances in next-generation sequencing techniques allow the detection of a large number of SNPs and their use in a high throughput manner. However, Cleaved Amplified Polymorphic Sequences (CAPSs) still play a significant role as complement to other high throughput methods for SNP genotyping. Therefore, new methods focusing on the acceleration of this type of markers are highly desirable. The combination of the classical CAPS technique and a M13-tailed primer multiplexing assay was used to develop an agarose gel free protocol for the analysis of SNPs via restriction enzyme digestion. PCR products were fluorescence labeled with a universal M13 primer and subsequently digested with the appropriate restriction endonuclease. After mixing differently labeled products, they were detected ...
[摘要] 新一代测序技术的最新进展允许以高通量方式检测大量的SNP及其使用。然而，裂解扩增多态性序列（CAPS）仍然作为补充其他高通量方法为SNP基因分型发挥重要作用。因此，非常需要关注于加速这种类型的标记的新方法。使用经典CAPS技术和M13尾引物多重测定的组合开发用于通过限制酶消化分析SNP的无琼脂糖凝胶方案。 PCR产物用通用M13引物进行荧光标记，随后用适当的限制性内切酶消化。在混合不同标记的产物后，在毛细管电泳系统上检测它们。该方法允许在短时间内以整体低成本以多路复用的方式进行成本有效的几种SNP的基因分型。此外，该方法可以有效地与在同一电泳运行中同时检测SSR组合，导致非常适合于基于标记的选择程序，绘图群体的基因分型和遗传多样性测定的程序。
