一般說明

DAPI（4′,6-二脒基-2-苯基吲哚二盐酸盐）是一种可与DNA结合的细胞可通透荧光染料。

應用

在琼脂糖凝胶中染色DNA，DAPI比溴化乙锭敏感几倍。它可用于DNA的光足迹图谱，通过对双链复合体的特殊可视化检测印迹应用中的退火探针，并使用流式细胞分析术研究DNA中的变化并分析凋亡过程中的DNA含量。DAPI染色也是一种敏感和特异的支原体检测方法。
适用于
  • 琼脂糖凝胶中的DNA染色
  • 分析凋亡过程中DNA的变化
  • 支原体检测
  • DNA的光足迹图谱
  • 细胞的免疫荧光染色

DAPI已用于：
  • 微生物污染的快速监测
  • 染色体条带技术
  • 凋亡细胞的检测
  • 在荧光显微镜中追踪DisA（DNA完整性扫描蛋白）在枯草芽孢杆菌DNA上的移动
  • 对成熟的花粉粒进行染色（0.5 mg/ml）

生化／生理作用

DNA的细胞渗透性荧光小沟结合探针。与双链DNA的小沟（富含AT的DNA优先）结合，形成稳定的复合物，其发出的荧光比单独的DAPI高约20倍。

注意

避光保存。
