    • The invention provides ligation reaction mixtures, methods, and kits for improved template-independent intramolecular ligation (circularization) of linear ssDNA, including denatured gDNA fragments or first-strand cDNA made by reverse transcription of RNA, using, for example, a thermostable RNA ligase. The circular ssDNA molecules obtained using the improved ligation reaction mixtures and methods can be used, for example, as templates: for amplification by inverse PCR, rolling circle replication, transcription, or for massively parallel DNA sequencing. Applications include, for example: gene expression analysis by qPCR or using microarrays; analysis of gDNA copy number variation; and detection or quantification of specific nucleic acid sequences for research, screening, medical diagnostics, theranostics, personalized medical treatment or breeding, for purposes such as human or animal medicine, forensics, or agriculture.
    • 本发明提供了用于改进线性ssDNA的模板无关分子内连接(环化)的连接反应混合物,方法和试剂盒,其包括使用例如热稳定的RNA连接酶,通过逆转录RNA制备的变性gDNA片段或第一链cDNA 。 使用改进的连接反应混合物和方法获得的环状ssDNA分子可用于例如模板:用于通过反向PCR扩增,滚环复制,转录或大规模并行DNA测序。 应用包括例如:通过qPCR进行基因表达分析或使用微阵列; 分析gDNA拷贝数变异; 检测或定量用于研究,筛选,医学诊断,治疗,个性化医疗或育种的特定核酸序列,用于人或动物医学,法医学或农业学等。
