High-resolution melt (HRM) analysis can identify sequence polymorphisms by comparing the melting curves of amplicons generated by real-time PCR amplification. We describe the application of this technique to identify Mycobacterium avium subspecies paratuberculosis types I, II, and III. The HRM approach was based on type-specific nucleotide sequences in MAP1506, a member of the PPE (proline-proline-glutamic acid) gene family.
高分辨率熔解(HRM)分析可以通过比较实时 PCR 扩增产生的扩增子的熔解曲线来识别序列多态性。我们描述了该技术在鉴定禽分枝杆菌亚种副结核分枝杆菌 I、II 和 III 型中的应用。HRM 方法基于 MAP1506 中的种特异性核苷酸序列,MAP1506 是 PPE(脯氨酸-脯氨酸-谷氨酸)基因家族的一个成员。
