efficiency of nucleotide incorporation during PCR was assessed with a multi-parameter hybridization analysis using a diagnostic DNA microarray. The hybridization analysis indirectly estimates the incorporation efficiency of dye-labeled nucleotides in multiplex PCR. Our results demonstrated higher efficiencies of substrates with electrically neutral dyes than electropositive and electronegative Cy5 residues
这项研究调查了Cy5标记的dUTP衍生物的合成和底物特性,这些衍生物具有不同的取代基,染料单元和嘧啶杂环之间的连接基以及荧光团电荷。使用Taq和Vent(exo-)DNA聚合酶(A和B聚合酶家族的典型代表)进行多重PCR,研究了荧光标记的三磷酸核苷作为底物。PCR期间核苷酸掺入的效率通过使用诊断DNA微阵列的多参数杂交分析进行评估。杂交分析间接估计了染料标记核苷酸在多重PCR中的掺入效率。我们的结果表明,与电正性和负电性Cy5残基相比,具有电中性染料的底物效率更高。
