could not. This dUthioTP fluorescent nucleotide could be used for the detection of miRNA 24-3P, which is related PRRSV. This direct labeling system during rolling circle DNA amplification exhibited an increased fluorescence signal showing gel formation for the detection of miRNA 24-3P. This direct labeling system is a very simple and cost-efficient method for the detection miRNA 24-3P and also exhibited

噻吩,
蒽和pyr中设计并合成了几种大小不同的荧光核苷酸,并筛选了它们在DNA滚环扩增过程中的掺入和延伸能力。基于
噻吩的荧光核苷酸(dUthioTP)可以高度整合并延伸到滚环DNA产品中,而其他荧光核苷酸(dUanthTP和dUpyrTP)则不能。该dUthioTP荧光核苷酸可用于检测与PRRSV相关的miRNA 24-3P。在滚环DNA扩增过程中,这种直接标记系统显示出增加的荧光信号,表明用于检测miRNA 24-3P的凝胶形成。
