Analysis Note

已通过斑点杂交试验测试功能。

Application

第二代寡核苷酸3′末端地高辛标记试剂盒采用DIG-11-ddUTP和重组末端转移酶对14-100bp的寡核苷酸进行3′-末端标记。
DIG标记寡核苷酸已用于多种杂交技术:
  • 斑点/狭缝印迹
  • 菌落/斑块杂交
  • Southern印迹/Northern印迹
  • 原位杂交

Biochem/physiol Actions

利用重组末端转移酶将一个DIG-ddUTP分子添加到寡核苷酸的3′-末端。这能够确保获得具有高特异性和独特性的杂交信号,该信号可利用酶联免疫测定结合抗DIG-AP抗体偶联物以及一种有色或化学发光反应进行检测。

Features and Benefits

  • 由于寡核苷酸具有小分子量,可用于快速杂交动力学
  • 单链探针,在杂交过程中不会复性
  • 可以根据实验设计序列
  • 特别适用于原位杂交;由于寡核苷酸具有小分子量,因此易于扩散到固定的组织和细胞中

General description

我们致力于为您提供更环保的替代产品,以符合“绿色化学的12项原则”的一项或多项原则要求。该产品为一种安全的化学品。  DIG系统是灵敏且具有成本效益的方案,可替代放射性标记和放射法检测核酸。有许多已发表论文证明了DIG系统的通用性,因此,使用放射性标记不再是标记用于杂交的DNA的唯一选择。
第二代寡核苷酸3′末端地高辛标记试剂盒使用了末端转移酶,可将单个地高辛标记双脱氧尿苷三磷酸(ddUTP)催化添加到寡核苷酸的3′-OH端上,从而标记寡核苷酸。
