Molecules 2-5 that include in their structure a biotin moiety as detectable unit and differently substituted phenyl diazo functions as reactive group were prepared as reagents for labeling the phosphate group in mono and polynucleotides. These molecules were shown to react selectively and quantitatively with the model nucleotide 3'-UMP. They were used successfully in the labeling step of DNA and RNA
制备在其结构中包括
生物素部分作为可检测单元并且不同取代的苯基重氮官能团作为反应性基团的分子2-5,作为标记单和多核苷酸中
磷酸基团的试剂。这些分子显示出与模型核苷酸3'-
UMP选择性和定量反应。它们已使用高密度DNA芯片(或微阵列)技术成功用于DNA和RNA分析的标记步骤。
